CUET UG Geography Booster Test 2-Conventional Energy Resources

According to the physical and economic geography of Indian energy minerals, India's coal reserves belong predominantly to the Gondwana geological age. Within these deposits, approximately 80 percent of the total available coal belongs to the bituminous variety. Furthermore, this coal is classified as non-coking grade, meaning it contains higher ash content and cannot be directly utilized in blast furnaces without blending. Instead, its abundant thermal capacity is harnessed as the main combustion fuel across the country's extensive network of thermal power stations. This fact directly supports option B as the correct answer.

Iron and steel manufacturing plants rely on specific mineral combinations for core blast furnace operations. Statement I is analytically correct because metallurgical coking coal serves as an irreplaceable raw material that generates the high thermal environment and the carbon monoxide gas required to reduce iron ore into molten iron. Statement II is also correct because manganese is a vital raw material added during the smelting and steel-making process to remove impurities like sulfur and to increase the basic tensile strength and hardness of the alloy. Since both statements represent accurate mineral utilities, option C is the correct answer.

This question requires direct retrieval of information from the text passage. The passage states: "The most important Gondwana coal fields of India are located in Damodar Valley." It also specifies in the second sentence that: "About 80 per cent of the coal deposits in India is of bituminous type..." Combining these explicit statements confirms that the Damodar Valley deposits belong to the Gondwana geological age and are predominantly of the bituminous type. This directly aligns with option B.

This question evaluates direct reading comprehension of the provided passage. The final sentence of the text states: "Jharia is the largest coal field followed by Raniganj." This sentence establishes the relative hierarchy between the two major coal hubs in the Jharkhand-Bengal belt. This matches option C.

Tertiary coal fields occur in the geological formations of the northeastern frontier states. The four major states noted for these younger fuel reserves are Arunachal Pradesh, Assam, Meghalaya, and Nagaland. To arrange these states in alphabetical sequence: 1. Arunachal Pradesh (Starts with 'Ar') 2. Assam (Starts with 'As') 3. Meghalaya (Starts with 'M') 4. Nagaland (Starts with 'N') This alphabetical sequence corresponds exactly to the order 1, 2, 3, 4, making option D the correct choice.

Tertiary coal deposits in India occur mainly in the northeastern states and some northern regions. Namchik-Namphuk → Arunachal Pradesh: This coalfield is located in Changlang district and is an important Tertiary coal deposit. Kalakot → Jammu and Kashmir: This coalfield represents the Tertiary coal formations of the Himalayan region. Darangiri → Meghalaya: Located in the Garo Hills, Darangiri is one of the important coal-producing areas of Meghalaya. Makum → Assam: The Makum coalfield is among the major Tertiary coalfields of Assam. Thus, the correct sequence is: 1-A, 2-B, 3-C, 4-D → Option B

Crude petroleum is an organic liquid fuel trapped within the porous sedimentary strata of the earth. Statement I is incorrect because crude petroleum does not consist strictly of liquid compounds; it inherently contains various dissolved gases and lighter hydrocarbon chains that separate upon extraction. Statement II is correct because crude oil is highly variable; its precise chemical composition, viscosity, base type (paraffinic or asphaltic), color, and specific gravity differ depending on the organic matter of its source basin. Therefore, only statement II is correct, which corresponds to option C.

Crude petroleum undergoes processing in oil refineries, where it is split into various fractions. Beyond providing transport fuels like diesel and petrol, the refining process yields by-products such as naphtha, which forms the core raw material for petrochemical manufacturing. This sector uses these hydrocarbon feedstocks to synthesize essential industrial products, including chemical fertilizers, synthetic rubber, plastics, and synthetic fibers. Therefore, fertilizer fits perfectly into this industrial sequence, matching option B.

Statement I is historically accurate; commercial oil extraction in India began at Digboi, Assam, in 1901, and it remained the country's sole oil-producing site for over half a century until ONGC expanded exploration in 1956. Statement II is incorrect because the refinery built at Digboi is located directly adjacent to the active oil fields to process the crude locally, which classifies it as a field-based refinery model, not a market-based model. Therefore, only statement I is correct, making option A the correct answer.

Petroleum and natural gas are mineral fuels formed from the decomposition of organic matter trapped in ancient marine sediments. These liquid hydrocarbons migrate through porous layers and accumulate under impermeable rock caps. Consequently, all commercial oil deposits, including those at Naharkatiya and Moran in the Brahmaputra Valley of Assam, are found within sedimentary rock formations. Therefore, option C is correct.

Statement I is correct because Mumbai High is located on the Arabian Sea shelf, approximately 160 km northwest of the Mumbai coast line. Statement II is also correct because offshore exploratory drilling successfully identified this major oil field in 1973. Following the installation of offshore platforms like Sagar Samrat, commercial extraction and production began in 1976. Since 1976 is exactly three years after 1973, statement II is factually and mathematically accurate. Therefore, both statements are correct, making option C the right choice.

India's petroleum resources are mainly found in sedimentary basins. The western onshore oil belt of Gujarat contains several important oilfields. Ankaleshwar → Gujarat: One of India's important oil-producing fields located near the Gulf of Khambhat. Lunej → Gujarat: A significant oilfield belonging to the Gujarat petroleum belt. Kosamba → Gujarat: Another petroleum-producing area located in Gujarat. Digboi → Assam: Known as one of India's earliest oil-producing fields, located in the northeastern oil belt. Thus, the correct sequence is: 1-B, 2-B, 3-B, 4-D → Option A

Statement I is correct because India's western gas reserves, centered around Mumbai High, are directly supplemented by onshore fields in the Cambay Basin in Gujarat. Statement II is incorrect because the Cambay Basin is located along the western coast of India, bordering the Arabian Sea; it has no connection to East Coast energy systems. The premier natural gas asset along the East Coast is the Krishna-Godavari basin. Therefore, only statement I is true, which corresponds to option A.

While traditional petroleum production was centered in the western and northeastern regions, modern exploration has revealed significant hydrocarbon assets along the East Coast. Massive reserves of natural gas and oil have been located within the deepwater sediments of the Kaveri basin and the Krishna-Godavari basin. This discovery altered the country's energy infrastructure by creating an energy hub on the East Coast, making option B the correct answer.

Oil refineries process raw crude oil into usable fuels and chemical bases. A field-based refinery is constructed close to the extraction wells to minimize the transport costs of unrefined crude oil. The Digboi refinery in Assam, built in 1901 right alongside the local oil fields, is the classic historical example of this model. Therefore, option B is the correct choice.

Statement I is correct because a field-based refinery model prioritizes proximity to the raw material, minimizing transport costs for unrefined crude; Digboi in Assam sits directly on the extraction field, illustrating this approach. Statement II is also correct because a market-based refinery model prioritizes proximity to the final consumer market, refining crude oil transported from a distance; Barauni in Bihar represents this approach. Since both statements accurately define and illustrate these refinery models, option C is the correct answer.

Uranium deposits in India are associated with specific geological formations and mining locations. Dharwar Rocks → Core geological system hosting uranium: These ancient crystalline rocks provide favourable conditions for radioactive mineral occurrence. Singbhum Copper Belt → Jharkhand: Located in Jharkhand, this belt contains important uranium deposits along with copper resources. Jaduguda → Uranium mining area: It is one of India's earliest and most significant uranium mining sites. Monazite Sands → Coastal radioactive mineral deposits: These sands contain valuable radioactive minerals, especially thorium. Hence, the correct sequence is: 1-B, 2-A, 3-C, 4-D → Option A

India's heavy mineral placer sands containing monazite are found across multiple coastal stretches. To arrange the listed locations in geographical order from South to North along the Indian coastline: 1. Kollam district is located on the southwestern coast in Kerala (3 - furthest South). 2. Vishakhapatnam is located further north along the southeastern coast in Andhra Pradesh (2 - middle). 3. The Mahanadi river delta is located further north along the coast in Odisha (1 - furthest North). This South-to-North progression yields the sequence 3, 2, 1, which corresponds to option A.

Statement I is correct because India's nuclear energy program gained momentum following the setup of the Atomic Energy Institute at Trombay in 1954, which was later renamed the Bhabha Atomic Research Centre (BARC). Statement II is also correct because this institutional foundation led to the commissioning of several commercial atomic energy projects, starting with the Tarapur Atomic Power Station in Maharashtra in 1969. Since both statements accurately describe the development of India's nuclear infrastructure, option C is the correct answer.

India's nuclear power plants are distributed across different states based on resource availability, technological development, and strategic location. Kalpakkam → Tamil Nadu: Located near Chennai, it houses the Madras Atomic Power Station. Narora → Uttar Pradesh: Situated on the banks of the Ganga, it is an important nuclear facility in northern India. Kaiga → Karnataka: Located in the Western Ghats region near the Kali River. Tarapur → Maharashtra: India's first commercial nuclear power station, located on the western coast. Hence, the correct sequence is: 1-C, 2-A, 3-B, 4-D → Option A
