Answer Review
1 Consider the following properties of minerals:
I. They can only be of inorganic origin.
II. They possess a definite chemical and physical property.
Which of the statements given above is/are mathematically and factually correct according to geography?
Point 1: Minerals can form through both inorganic chemical processes and organic biological accumulation. Point 2: Organic mineraloids and fossil fuels like coal and petroleum originate from ancient living matter. Point 3: Each specific mineral possesses a fixed internal atomic structure, creating an identifiable set of chemical and physical properties.
Statement I is incorrect because minerals can be of both organic and inorganic origin. While most crystalline rock-forming minerals are inorganic, geography and geology textbooks classify organic hydrocarbon deposits—such as coal, petroleum, and natural gas—as organic non-metallic minerals. Statement II is correct because a mineral must possess a definite chemical composition and characteristic physical properties, which allow it to be classified and identified. Therefore, only Statement II is correct, validating Option B.
- Option A: This option is incorrect because it accepts Statement I, which wrongly excludes organic fuels from mineral classifications.
- Option C: This option is incorrect because Statement I contains an absolute falsehood by declaring minerals can only be inorganic.
- Option D: This option is incorrect because it rejects Statement II, failing to acknowledge that a definite chemical and physical setup is a mandatory requirement for any mineral.
Used: Extreme Word Filter
Application: Identify the extreme word "only" in Statement I. Because geography standard systems include organic fossil fuels under the broad umbrella of mineral resources, Statement I is eliminated.
Final Logic: Removing Statement I isolates Statement II as the sole correct option.
Minerals can be organic or inorganic in origin, but they must always have a definite property profile.
2 Match the mineral category with its accurate textbook example:
| List I (Mineral Category) | List II (Example) |
|---|---|
| 1. Ferrous metallic minerals | A. Mica |
| 2. Non-ferrous metallic minerals | B. Manganese |
| 3. Inorganic non-metallic minerals | C. Bauxite |
| 4. Organic non-metallic minerals | D. Coal |
Point 1: Ferrous minerals are associated with iron content and include manganese, which is widely used in steel production, making 1-B correct. Point 2: Non-ferrous metallic minerals do not contain iron and include bauxite, the chief ore of aluminium, making 2-C correct. Point 3: Inorganic non-metallic minerals include mica, which is a non-metallic mineral, making 3-A correct. Point 4: Organic non-metallic minerals are derived from organic matter and include coal, making 4-D correct. Therefore, the correct matching is 1-B, 2-C, 3-A, and 4-D, making Option A correct.
Ferrous metallic – Manganese (1-B): Ferrous minerals are those associated with iron and are important for the iron and steel industry. Manganese is classified under ferrous minerals because it is an essential raw material for steel manufacturing. Non-ferrous metallic – Bauxite (2-C): Bauxite is the chief ore of aluminium and does not contain iron, making it a non-ferrous metallic mineral. Inorganic non-metallic – Mica (3-A): Mica is a non-metallic mineral formed through geological processes and is widely used in electrical and industrial applications. Organic non-metallic – Coal (4-D): Coal is classified as an organic mineral because it is formed from accumulated plant remains over geological periods. Hence, the correct sequence is: 1-B, 2-C, 3-A, 4-D
- Option B: Incorrect because it places bauxite under ferrous minerals and misclassifies manganese.
- Option C: Incorrect because bauxite and coal are assigned to incorrect mineral categories.
- Option D: Incorrect because mica is not a ferrous mineral and manganese is not an organic non-metallic mineral.
Used: Classification-Based Elimination
Application:
- Identify the key examples:
- Ferrous → Manganese
- Non-ferrous → Bauxite
- Inorganic non-metallic → Mica
- Organic non-metallic → Coal
Final Logic:
- Matching each mineral with its correct category gives Option A as the correct answer.
Coal → Carbon-based organic mineral
3 An electrical industry needs a highly malleable and ductile non-ferrous mineral to manufacture transformers. Which of the following minerals perfectly fits this requirement?
Point 1: Electrical transformers require components that conduct electricity efficiently with minimal resistance losses. Point 2: The targeted resource must belong to the metallic non-ferrous category, meaning it cannot contain iron. Point 3: Copper is a highly ductile, non-ferrous metal widely used in electrical wiring and power machinery.
Copper is an indispensable non-ferrous metal in the electrical engineering industry. Its physical properties of high electrical conductivity, excellent ductility, and malleability make it the ideal raw material for manufacturing electrical cables, transformers, generators, and electronics. Because it possesses high metallic performance without the magnetic and corrosive issues of iron, it perfectly fits the industrial requirement, validating Option B.
- Option A: This option is incorrect because iron ore is a ferrous metallic mineral that does not possess the high electrical conductivity needed for transformer windings.
- Option C: This option is incorrect because mica is a non-metallic mineral used as an electrical insulator rather than a conductive wire element.
- Option D: This option is incorrect because graphite is a non-metallic crystalline form of carbon that cannot be drawn into ductile, flexible wires.
Used: Dimensional/Unit Analysis
Application: Break down the parameters: Malleable/Ductile Metal + Non-Ferrous + Electrical Conductor. Iron ore is ferrous (fails parameter 2), while mica and graphite are non-metallic (fail parameter 1).
Final Logic: Copper is the only resource that satisfies all three parameters.
Electrical wiring and transformers rely on copper because it is a highly conductive, non-ferrous metal.
4 Evaluate the following statements:
I. Minerals that do not have iron content are called non-ferrous metallic minerals.
II. Fossil fuels are derived from buried animal and plant life.
Which of the above accurately define their respective categories?
Point 1: Metallic minerals are divided into ferrous (containing iron) and non-ferrous (lacking iron) groups. Point 2: Fossil fuels form from prehistoric organic matter buried under deep sedimentary layers over millions of years. Point 3: Both sentences present accurate geographic and scientific definitions of these resource categories.
Both statements are accurate definitions of their resource groups. Statement I is true because non-ferrous metallic minerals are defined by the absence of iron content, with prominent examples including copper, bauxite, lead, and zinc. Statement II is true because organic non-metallic resources like coal, petroleum, and natural gas form from ancient plant and animal remains subjected to extreme heat and pressure over geological time. This makes Option C the correct choice.
- Option A: This option is incorrect because it leaves out Statement II, ignoring the organic biological origins of fossil fuels.
- Option B: This option is incorrect because it leaves out Statement I, ignoring the baseline classification rule for non-ferrous metals.
- Option D: This option is incorrect because it rejects both valid definitions, failing to recognize standard textbook resource classifications.
Used: Contextual/Tonal Matching
Application: Evaluate both sentences against standard geographical terminology. Both present standard, non-contradictory scientific definitions.
Final Logic: Since both statements are true, Option C is selected.
Non-ferrous means no iron, and fossil fuels come from ancient life.
5 Arrange the following major coal-bearing river valleys based on their spatial presence from North to South geographically in the peninsular plateau:
1. Damodar
2. Godavari
3. Mahanadi
Point 1: Gondwana coalfields are concentrated along major river basins in the eastern peninsular plateau. Point 2: The Damodar valley runs through Jharkhand and West Bengal in the northern section of the plateau. Point 3: The Mahanadi basin is located south of the Damodar in Odisha, while the Godavari basin is further south in Telangana and Andhra Pradesh.
This spatial question tracks India's primary Gondwana coal-bearing river valleys from North to South. The northernmost basin is the Damodar River Valley (1), which runs through Jharkhand and West Bengal and holds major coalfields like Jharia and Raniganj. Moving south, the next basin is the Mahanadi River Valley (3) in Odisha, known for the Talcher coalfields. The southernmost of the three is the Godavari River Valley (2), which extends into Telangana and Andhra Pradesh and contains the Singareni coalfields. This establishes the sequence as 1, 3, 2, validating Option A.
- Option B: This option is incorrect because it places the Godavari valley north of the Mahanadi, which reverses their physical geographic positions.
- Option C: This option is incorrect because it lists the Mahanadi valley as the northernmost point, ignoring the higher latitude of the Damodar valley.
- Option D: This option is incorrect because it places the southern Godavari basin at the start of the sequence.
Used: Dimensional/Unit Analysis
Application: Apply relative latitude coordinates to the river basins: Damodar (Jharkhand/WB ≈ 23°N) → Mahanadi (Odisha ≈ 21°N) → Godavari (Telangana/AP ≈ 17°N).
Final Logic: Ordering these latitudes from North to South creates the sequence 1, 3, 2, matching Option A.
Travel from North to South along the coal valleys by following the alphabetical order of their states: Damodar (Jharkhand) → Mahanadi (Odisha) → Godavari (Telangana).
6 There is a/an ________ relationship between the quality and quantity of minerals, meaning good quality minerals are less in quantity.
Point 1: Mineral deposits form through specific geological processes over long periods. Point 2: High-grade deposits with minimal impurities require rare geological conditions to form. Point 3: Because high-grade conditions are rare, high-quality deposits are much smaller than lower-grade reserves.
Geological surveys show that mineral resource quality and total volume share an inverse relationship. High-grade ores with a high concentration of pure metals are scarce and found in small, localized deposits. In contrast, low-grade ores with higher levels of impurities are far more common and form larger reserves worldwide. This inverse pattern means that as mineral quality increases, the total available volume decreases, validating Option C.
- Option A: This option is incorrect because a direct relationship would mean that high-grade minerals are the most abundant on Earth, which is false.
- Option B: This option is incorrect because proportional implies that quality and quantity grow together, which contradicts resource scarcity patterns.
- Option D: This option is incorrect because parallel is a geometric description that does not define statistical or resource distribution relationships.
Used: Contextual/Tonal Matching
Application: Identify the standard terminology used in geography text strings. The text explicitly defines the balance between quality and quantity as an "inverse relationship."
Final Logic: This exact phrase match rules out alternative options, pointing to Option C.
High grade means low abundance, making the resource relationship inverse.
7 Why do minerals need to be conserved strictly without misuse?
I. They do not have a second crop.
II. They can be replenished immediately at the time of need.
Which statement is logically correct based on their exhaustible nature?
Point 1: Minerals are non-renewable resources that cannot be grown or replanted like agricultural crops. Point 2: The geological processes that form minerals take millions of years to complete. Point 3: Once a mineral deposit is fully mined, it is permanently depleted, making Statement II false.
Statement I is correct because minerals are finite, exhaustible resources that do not produce a "second crop." Once an iron or copper mine is depleted, the resource is gone for good within a human timeframe. Statement II is incorrect because minerals form through slow geological processes over millions of years and cannot be replenished immediately when shortages occur. Because only Statement I is factually correct, Option A is the right choice.
- Option B: This option is incorrect because it validates Statement II, which mistakenly treats non-renewable minerals as instantly self-replenishing resources.
- Option C: This option is incorrect because Statement II is false, which invalidates any option accepting both statements.
- Option D: This option is incorrect because it rejects Statement I, failing to acknowledge that minerals are finite resources with no secondary crop.
Used: Contextual/Tonal Matching
Application: Evaluate Statement II from an environmental science perspective. The idea that finite minerals can be replenished immediately is false, allowing Statement II to be eliminated.
Final Logic: Removing Statement II leaves Statement I as the correct choice.
Minerals are finite resources with no second crop, making long-term conservation essential.
8 Arrange the following geological ages associated with Indian mineral and coal deposits from oldest to youngest:
1. Pre-Palaeozoic age
2. Gondwana period
3. Tertiary period
4. Quaternary period
Point 1: The Pre-Palaeozoic age represents the oldest geological formations in India, forming the ancient crystalline rocks of the Peninsular Plateau. Point 2: The Gondwana period is younger than the Pre-Palaeozoic age and is associated with major coal deposits of India. Point 3: The Tertiary period is much younger and is linked with younger sedimentary formations, petroleum deposits, and lignite coal. Point 4: The Quaternary period is the youngest geological period associated with recent deposits and alluvial formations. Therefore, the correct chronological order is: Pre-Palaeozoic → Gondwana → Tertiary → Quaternary making Option B correct.
Pre-Palaeozoic Age (1): These are the oldest geological formations in India. The ancient crystalline rocks formed during this period contain important metallic minerals such as iron ore, manganese, and mica. Gondwana Period (2): The Gondwana formations are younger than the ancient rocks and are famous for containing India's major coal reserves, especially in the Damodar valley. Tertiary Period (3): The Tertiary formations belong to a much later geological period and are associated with younger deposits such as petroleum and lignite. Quaternary Period (4): This is the most recent geological period and includes recent alluvial deposits formed by rivers. Hence, the correct sequence from oldest to youngest is: 1 → 2 → 3 → 4
- Option A: Incorrect because it reverses the geological timeline by placing the youngest period first.
- Option C: Incorrect because Gondwana formations are not older than Pre-Palaeozoic rocks.
- Option D: Incorrect because Tertiary formations are younger than Gondwana and Pre-Palaeozoic formations.
Used: Chronological Ordering
Application:
- Arrange geological periods based on their position in Earth's history:
- Ancient foundation → Pre-Palaeozoic
- Coal formation → Gondwana
- Younger mineral deposits → Tertiary
- Recent deposits → Quaternary
Final Logic:
- The correct oldest-to-youngest order is 1, 2, 3, 4, making Option B correct.
Q → Quaternary: Quick recent formations
9 Match the mineral belt with its defining characteristic:
| List I (Mineral Belt) | List II (Characteristic) |
|---|---|
| 1. North-Eastern Plateau Region | A. Lacks diversified mineral deposits and major coal reserves except Neyveli lignite |
| 2. South-Western Plateau Region | B. Contains a rich variety of minerals including iron ore, coal, manganese, bauxite, and mica |
| 3. North-Western Region | C. Associated mainly with petroleum and natural gas resources |
| 4. Himalayan Region | D. Poor in metallic mineral resources due to young geological formations |
Point 1: The North-Eastern Plateau Region is the richest mineral belt of India, containing iron ore, coal, manganese, bauxite, and mica deposits, making 1-B correct. Point 2: The South-Western Plateau Region has important iron ore deposits but lacks diversified coal resources except for Neyveli lignite, making 2-A correct. Point 3: The North-Western Region is associated mainly with petroleum and natural gas resources, making 3-C correct. Point 4: The Himalayan Region has fewer metallic mineral deposits because of its younger geological structure, making 4-D correct. Therefore, the correct matching is 1-B, 2-A, 3-C, and 4-D, making Option A correct.
North-Eastern Plateau Region – Rich mineral diversity (1-B): This region includes the Chhotanagpur Plateau and Odisha plateau areas. It is one of India's most important mineral zones, containing deposits of iron ore, coal, manganese, bauxite, and mica. South-Western Plateau Region – Limited coal and diversified deposits (2-A): This region includes parts of Karnataka and Tamil Nadu. It has valuable iron ore and manganese deposits but lacks extensive coal reserves. The Neyveli lignite deposits are an important exception. North-Western Region – Petroleum and natural gas (3-C): The sedimentary basins of this region contain important petroleum and natural gas resources. Himalayan Region – Poor metallic mineral resources (4-D): Due to its young geological formations and complex structure, the Himalayas have limited deposits of metallic minerals. Hence, the correct sequence is: 1-B, 2-A, 3-C, 4-D
- Option B: Incorrect because it reverses the characteristics of the North-Eastern and South-Western plateau regions.
- Option C: Incorrect because it incorrectly links the South-Western region mainly with petroleum resources.
- Option D: Incorrect because it wrongly classifies the mineral-rich North-Eastern Plateau as poor in resources.
Used: Regional Association Method
Application:
- Remember the key mineral identity of each belt:
- North-Eastern Plateau → Variety of minerals + coal
- South-Western Plateau → Iron ore rich, coal limited
- North-Western Region → Petroleum and gas
- Himalayan Region → Poor metallic minerals
Final Logic:
- Matching each mineral belt with its defining feature gives Option A as correct.
Himalayas → Limited metallic minerals
10 If an industrialist wants to establish a metallurgical plant relying on old crystalline rocks rich in metallic minerals, which macro-region should they strategically target?
Point 1: Metallurgical plants require steady access to high-grade metallic ores like iron and manganese. Point 2: These metallic minerals are concentrated within ancient igneous and metamorphic crystalline structures. Point 3: The Peninsular Plateau is the primary macro-region in India made of these old crystalline rocks.
An industrialist looking to build a metallurgical plant should target the Peninsular Plateau Region. This macro-region is one of Earth's ancient stable landmasses, composed of old crystalline igneous and metamorphic rocks. Over geological time, volcanic activity and crustal metamorphism concentrated large deposits of metallic ores—such as iron ore, manganese, bauxite, and chromite—within this plateau, making it the ideal location for heavy metallurgical industries and validating Option B.
- Option A: This option is incorrect because the Northern Alluvial Plains consist of young river silt deposits that are poor in metallic mineral ores.
- Option C: This option is incorrect because the Himalayan Mountains feature complex, disrupted rock layers that make large-scale, systematic metallurgical mining difficult.
- Option D: This option is incorrect because the Coastal Plains consist of loose marine and river sediments that lack the old crystalline bedrock needed for metallic ore veins.
Used: Contextual/Tonal Matching
Application: Connect the geological environment with its corresponding geographic macro-region. The phrase "old crystalline rocks rich in metallic minerals" points directly to the Peninsular Plateau.
Final Logic: This geological connection makes Option B the correct answer.
Heavy industries target the Peninsular Plateau because its old crystalline rocks hold the bulk of India's metallic ores.
11 Which statement explains the severe limitation of mineral extraction in northern India?
I. The vast alluvial plain tract is rich in fossil fuels but lacks metallic minerals.
II. The vast alluvial plain tract of north India is completely devoid of minerals of economic use.
Point 1: The northern plains consist of thick layers of river-deposited silt that cover the older bedrock below. Point 2: This deep layer of loose soil contains neither metallic ores nor fossil fuel reserves like coal or oil. Point 3: Because the region lacks these resources, textbooks describe the northern alluvial plains as being devoid of minerals of economic use.
Statement II is correct because the vast alluvial plains of northern India are composed of thick, young river silt that contains no major mineral deposits of economic value. Statement I is incorrect because these plains do not contain fossil fuels; India's primary fossil fuels are located in the Gondwana basins of the peninsula and the Tertiary sedimentary basins of Assam and Gujarat. Because the deep silt layers in the north cover up older, mineral-bearing rock formations, the region lacks both metallic ores and fossil fuels, making Statement II the only correct answer and validating Option B.
- Option A: This option is incorrect because Statement I wrongly claims the northern agricultural plains are rich in fossil fuels.
- Option C: This option is incorrect because it validates Statement I, ignoring the fact that the northern plains lack major coal or petroleum reserves.
- Option D: This option is incorrect because it rejects Statement II, failing to recognize that the northern plains lack economic mineral resources due to their deep alluvial soils.
Used: Contextual/Tonal Matching
Application: Check the resource profiles for each region. The northern plains are prime agricultural lands but lack both metallic ores and fossil fuels.
Final Logic: This lack of minerals confirms Statement II is true and Statement I is false, making Option B correct.
The northern alluvial plains are rich in fertile soil for farming but are devoid of economic minerals.
12 While the northern plains lack resources, the Himalayan belt shows potential as copper, lead, zinc, ________, and tungsten are known to occur.
Point 1: The Himalayan range formed through tectonic activity that altered and dislocated rock layers. Point 2: This tectonic activity created scattered deposits of non-ferrous base metals along the mountain belt. Point 3: The textbook explicitly lists copper, lead, zinc, cobalt, and tungsten as minerals found within this mountain system.
The Himalayan mountain belt has a distinct mineral profile shaped by tectonic activity. The intense pressure and rock displacement along the range created scattered deposits of base and non-ferrous metals. The textbook lists these specific minerals as copper, lead, zinc, cobalt, and tungsten. While these deposits are often scattered and difficult to mine systematically, they represent significant potential resources, validating Option C.
- Option A: This option is incorrect because bauxite is a surface-weathered clay mineral found on flat plateau tops like Amarkantak rather than in folded mountain belts.
- Option B: This option is incorrect because India's major iron ore reserves are located within the ancient crystalline rocks of the peninsular shields rather than the younger Himalayan formations.
- Option D: This option is incorrect because monazite is a heavy sand mineral concentrated along coastal beaches, particularly in Kerala, rather than in alpine mountain ranges.
Used: Contextual/Tonal Matching
Application: Identify the exact list of minerals associated with the Himalayas in geography textbooks. The text groups non-ferrous base metals together: copper, lead, zinc, cobalt, and tungsten.
Final Logic: This textbook grouping highlights cobalt as the correct missing term.
The tectonic rocks of the Himalayas contain a distinct group of base metals, including cobalt and tungsten.
13
Point 1: The iron and steel industry is a weight-losing industry that depends on heavy raw materials. Point 2: Shipping these heavy raw materials long distances adds significant transportation costs for factories. Point 3: The passage notes that the industry is located here because the region contains a variety of minerals, including iron ore and coal.
The provided passage explains why the iron and steel industry is concentrated in the North-Eastern Plateau Region. The text asks why these factories are located in the area and answers by stating: "It has variety of minerals viz. iron ore coal, manganese, bauxite, mica." Because iron manufacturing requires large amounts of iron ore, metallurgical coal, and manganese, building plants near these shared deposits minimizes transportation costs, validating Option B.
- Option A: This option is incorrect because while coastal ports help with international trade, the passage focuses on the region's inland mineral deposits as the primary draw for the industry.
- Option C: This option is incorrect because old crystalline rocks alone do not guarantee extractable mineral wealth unless they contain specific, accessible ore veins.
- Option D: This option is incorrect because the region's distance from the Himalayas is a general geographic fact that does not explain why heavy industries choose to locate there.
Used: Contextual/Tonal Matching
Application: Look at the final sentence of the passage. The text explicitly connects the location of the iron and steel industry with the local presence of iron ore, coal, and manganese.
Final Logic: This direct connection points to Option B as the correct answer.
The passage indicates that iron and steel plants are built here because the region holds the necessary raw materials, like iron ore and coal.
14
Point 1: The passage outlines the geographic boundaries of the North-Eastern Plateau mineral belt. Point 2: This economic zone spans several states across east-central India. Point 3: The first sentence of the passage explicitly names Jharkhand, Odisha, West Bengal, and Chhattisgarh.
The passage explicitly lists the states that make up the North-Eastern Plateau Belt. The first sentence reads: "This belt covers Chhotanagpur (Jharkhand), Odisha Plateau, West Bengal and parts of Chhattisgarh." Of the choices provided, West Bengal is the only state explicitly named in the text, validating Option C as the correct answer.
- Option A: This option is incorrect because Karnataka is located in southern India and forms the core of the South-Western Plateau Belt.
- Option B: This option is incorrect because Gujarat is located on the western coast and belongs to the North-Western Region Belt.
- Option D: This option is incorrect because Kerala is situated on the southwestern coast and is known for its coastal beach sand deposits.
Used: Contextual/Tonal Matching
Application: Review the first sentence of the passage to identify the listed states. Cross-referencing this list with the options isolates the correct choice.
Final Logic: This direct text match confirms Option C is the correct answer.
The passage explicitly names West Bengal as part of this eastern mineral-producing belt.
15 Arrange the following states from North to South based on their location in the South-Western Plateau mineral belt:
1. Goa
2. Karnataka
3. Kerala
Point 1: The South-Western Plateau Belt runs along the western side of the Indian peninsula. Point 2: Goa is located along the Konkan coast at a higher latitude (≈ 15°N). Point 3: Karnataka lies directly south of Goa, while Kerala extends further south along the Malabar coast toward Cape Comorin.
This geographic question tracks the states of the South-Western mineral belt from North to South. The northernmost state in this group is Goa (1), known for its coastal iron ore export mines. Moving south leads into Karnataka (2), which holds major iron ore and manganese reserves in the Baba Budan and Sandur ranges. Continuing south leads to Kerala (3), which forms the southern end of the belt and is known for its monazite beach sands. This establishes the North-to-South sequence as 1, 2, 3, validating Option B.
- Option A: This option is incorrect because it places Karnataka north of Goa, which reverses their actual geographic positions along the western coast.
- Option C: This option is incorrect because it reverses the order entirely, listing the southernmost state, Kerala, first.
- Option D: This option is incorrect because it places Kerala north of Karnataka, which is geographically incorrect in the peninsular sequence.
Used: Dimensional/Unit Analysis
Application: Apply relative latitudes to the states along the western coast: Goa (≈ 15.5°N) → Karnataka (≈ 13°N) → Kerala (≈ 10°N).
Final Logic: Ordering these positions from North to South confirms 1, 2, 3 as the correct sequence, matching Option B.
Move down the western coast from North to South by following the alphabetical order of the states: Goa (1) → Karnataka (2) → Kerala (3).
16 Consider the resources of Kerala:
I. It has deposits of monazite, thorium, and bauxite clay.
II. It is India's leading producer of Gondwana coal.
Which statement(s) is/are correct?
Point 1: Kerala's coastal beach sands contain concentrations of monazite, which is a key source of thorium. Point 2: The region's rock formations also include local deposits of bauxite-grade clays. Point 3: Gondwana coal fields are located in eastern states like Jharkhand and Odisha, making Statement II false.
Statement I is correct because Kerala's coastal and geological resources include significant monazite and thorium sand deposits, along with local bauxite clays. Statement II is incorrect because Kerala does not contain Gondwana coal fields. India's Gondwana coal reserves are located in the eastern river valleys of Jharkhand, Odisha, Chhattisgarh, and West Bengal. Because the South-Western Belt lacks these coal fields, Statement II is false, making Option A the correct choice.
- Option B: This option is incorrect because it validates Statement II, which mistakenly places India's primary coal production fields in Kerala.
- Option C: This option is incorrect because it accepts Statement II, ignoring the fact that Gondwana coal is concentrated in eastern India.
- Option D: This option is incorrect because it rejects Statement I, failing to recognize Kerala's monazite and thorium beach sand resources.
Used: Contextual/Tonal Matching
Application: Evaluate the regional distribution of coal. Gondwana coal is found in the eastern river basins, which means Statement II can be eliminated.
Final Logic: Removing Statement II leaves Statement I as the correct choice.
Kerala is known for its coastal monazite sands, but lacks the Gondwana coal fields found in eastern India.
17 In the North-Western Region, minerals are strongly associated with the ________ system of rocks.
Point 1: The North-Western mineral belt extends across the ancient geological formations of Rajasthan. Point 2: The Aravali mountain range consists of ancient, metamorphosed rock layers. Point 3: The textbook states that minerals in this region are associated with the Dharwar system of rocks.
The mineral deposits of the North-Western Region—which extends along the Aravali range in Rajasthan—are associated with the Dharwar system of rocks. This ancient geological rock system consists of metamorphosed sediments and crystalline layers that contain deposits of non-ferrous metals like copper, lead, and zinc, along with industrial stones like marble and gypsum, validating Option C.
- Option A: This option is incorrect because Tertiary rocks are younger formations associated with petroleum reserves rather than the ancient metal-bearing bedrock of the Aravalis.
- Option B: This option is incorrect because Gondwana rocks are upper-palaeozoic sedimentary formations that contain India's primary coal fields in the eastern peninsula.
- Option D: This option is incorrect because Cenozoic formations are younger rocks associated with the creation of the Himalayas and northern alluvial soils.
Used: Contextual/Tonal Matching
Application: Match the mineral belt with its rock system. Geography textbooks link the metal ores of the Aravali range with the ancient Dharwar rock system.
Final Logic: This geological pairing rules out the younger rock systems, confirming Option C.
The ancient non-ferrous metals of the North-Western Aravalis are held within the Dwarwar rock system.
18 Match the states in the North-Western belt with their primary non-metallic/fuel resources:
| List I (State) | List II (Resource) |
|---|---|
| 1. Rajasthan | A. Petroleum deposits |
| 2. Gujarat | B. Gypsum, Fuller's earth, and building stones |
| 3. Haryana | C. Limestone and other construction minerals |
| 4. Punjab | D. Minor mineral resources with limited metallic deposits |
Point 1: Rajasthan is known for non-metallic minerals such as gypsum, Fuller's earth, and building stones, making 1-B correct. Point 2: Gujarat's sedimentary basins contain important petroleum deposits, making 2-A correct. Point 3: Haryana has deposits of construction-related minerals such as limestone, making 3-C correct. Point 4: Punjab has limited mineral resources compared to other states of the belt, making 4-D correct. Therefore, the correct matching is 1-B, 2-A, 3-C, 4-D, making Option B correct.
Rajasthan – Gypsum, Fuller's earth, and building stones (1-B): Rajasthan's arid and sedimentary regions contain valuable non-metallic minerals. It is especially known for gypsum, Fuller's earth, marble, and sandstone used in construction. Gujarat – Petroleum deposits (2-A): Gujarat's sedimentary basins contain important petroleum reserves. Major oil fields such as Ankleshwar and Kalol contribute to India's petroleum production. Haryana – Construction minerals (3-C): Haryana has deposits of minerals used mainly for building and construction activities. Punjab – Limited mineral resources (4-D): Punjab has fewer mineral resources because of its alluvial plains and geological conditions. Hence, the correct sequence is: 1-B, 2-A, 3-C, 4-D
- Option A: Incorrect because Rajasthan is not primarily known for petroleum deposits; Gujarat is the major petroleum state in this pair.
- Option C: Incorrect because it assigns petroleum resources to both Rajasthan and Gujarat.
- Option D: Incorrect because it ignores Gujarat's major petroleum resources.
Used: State–Resource Association
Application:
- Identify the unique resource associated with each state:
- Rajasthan → Gypsum + Fuller's earth + Building stones
- Gujarat → Petroleum deposits
Final Logic:
- Matching Rajasthan with industrial minerals and Gujarat with petroleum gives Option B as correct.
Gujarat → Gas and petroleum
19 Which of the following interventions exemplifies a strategy to replace exhaustible resources in alignment with Sustainable Development Goals?
Point 1: Sustainable development requires moving away from finite, exhaustible resources to prevent resource depletion. Point 2: Fossil fuels generate carbon emissions and cannot be replenished once consumed. Point 3: Developing renewable energy sources like solar and wind power replaces finite fuels with clean, inexhaustible alternatives.
Developing alternative energy sources like solar and wind power directly supports sustainable development goals by replacing exhaustible resources. Fossil fuels like coal and oil are finite and cause environmental degradation when used. Switching to inexhaustible sources helps protect the environment and ensures future generations have access to a stable energy supply, validating Option B.
- Option A: This option is incorrect because increasing the export of scarce minerals accelerates the depletion of domestic reserves, running counter to conservation goals.
- Option C: This option is incorrect because discovering new coal deposits uncovers more fossil fuels, which does not replace the resource with a sustainable alternative.
- Option D: This option is incorrect because while scrap metal recycling is a valuable conservation practice, it extends the life of existing metals rather than replacing an exhaustible resource with an inexhaustible one.
Used: Contextual/Tonal Matching
Application: Focus on the phrase "replace exhaustible resources." The correct choice must replace a finite resource with an inexhaustible or renewable alternative, such as solar or wind power.
Final Logic: This focus on renewable energy highlights Option B as the correct answer.
To replace finite, exhaustible resources sustainably, shift toward inexhaustible energy sources like solar and wind power.
20 Evaluate the rationale for recycling scrap metal:
I. Use of scrap is especially significant in metals like copper, lead, and zinc.
II. It is significant because India's natural reserves of these metals are meagre.
Which is true?
Point 1: India has limited domestic reserves of certain non-ferrous base metals like copper, lead, and zinc. Point 2: Because domestic reserves are limited, the country relies on imports to meet industrial demand. Point 3: Recycling scrap metal helps reduce this import reliance and conserves scarce domestic resources.
Both statements are correct and support each other. Statement I is true because recycling scrap metal is crucial for managing non-ferrous base metals like copper, lead, and zinc. Statement II provides the reason why, noting that India's domestic reserves of these specific metals are limited. Developing scrap recycling systems helps secure a domestic supply of these metals, reduces reliance on imports, and saves energy during manufacturing, validating Option C.
- Option A: This option is incorrect because it leaves out Statement II, missing the underlying reason why scrap recycling is so critical for these metals.
- Option B: This option is incorrect because it leaves out Statement I, omitting the specific metals affected by this resource scarcity.
- Option D: This option is incorrect because it rejects both valid statements, failing to recognize how scrap recycling helps address domestic resource shortages.
Used: Contextual/Tonal Matching
Application: Evaluate how the statements relate to each other. Statement I names the specific target metals, and Statement II explains the geological scarcity that makes recycling them necessary.
Final Logic: Because both statements are true and work together logically, Option C is the correct answer.
India has limited natural reserves of copper, lead, and zinc, making scrap metal recycling essential to maintain supplies.
