Test: Mineral & Energy Resources - 1 - UPSC MCQ

C is the correct option.Minerals are found in layers or strata in sedimentary rocks. Minerals are accumulated in horizontal strata after being exposed to high heat and pressure for a long period of time. Coal, iron ore, gypsum, potash salt etc are formed in this way.

Explanation:
- Gypsum is the mineral that is formed as a result of evaporation in arid regions.
- It forms through the process of crystallization when water containing dissolved calcium sulfate evaporates.
- Zinc, coal, and copper are not formed through evaporation in arid regions.

B is the correct option.Bauxite is a mineral which is formed by decomposition of rocks, leaving a residual mass of weathered material.

B is the correct option.Most of the minerals in India are nationalised and they can be extracted with due permission of the government. ... Mining of minerals like coal, iron ore, limestone, dolomite, etc., is done by family members in the form of a long narrow tunnel, known as 'Rat-hole Mining'.
Rat-hole mining is a primitive and hazardous method of mining for coal, with tunnels that are only 3-4 feet in diameter (hence, rat-hole), leading to pits ranging from 5-100 sq.
 

The correct answer is A as Bauxite is found mainly in tertiary deposits and is associated with laterite rocks occurring extensively either on the plateau or hill ranges of peninsular India and also in the coastal tracts of the country. Odisha happens to be the largest producer of Bauxite.

D is the correct option.Koderma district is rich in minerals. The Koderma district and the Lokai-Indarwa area covers the southern part of Great Mica-Belt of Jharkhand, Bihar, and India.

A is the correct option.Atomic energy a non-conventional energy resource. Nuclear power has never provided more than about 2% of the world's energy demand (10% of demand is electricity and 20% of that is nuclear over about 50 years. )

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content.

B is the correct option.About 63 per cent of India's petroleum production is from Mumbai High, 18 per cent from Gujarat and 16 per cent from Assam.

C is the correct option.Uranium and Thorium, which are available in Jharkhand and the Aravalli ranges of Rajasthan are used for generating atomic or nuclear power. The Monazite sands of Kerala is also rich in Thorium.

C is the correct option. Nagercoil and Jaisalmer are well known for effective use of wind energy in the country.

In India, the Gulf of Kachchh, provides ideal conditions for utilising tidal energy. A 900 mw tidal energy power plant is set up here by the National Hydropower Corporation.
In India, the tidal energy is generated in Gulf of Khambhat, the Gulf of Kuchchh in Gujarat and Gangetic delta. 

B is the correct option.Khetri is actually two towns, "Khetri Town" founded by Raja Khet Singhji Nirwan and "Khetri Nagar" which is about 10 km away from Khetri. Khetri Nagar, well known for its “Copper” Project, was built by and is under the control of Hindustan Copper Limited, a public sector undertaking under the Government of India.

The most recoverable form of bromine is from soluble salts found in seawater, salt lakes, inland seas and brine wells. Sea water contains bromine in about 65 parts per million (ppm) but bromine is found in much higher concentrations (2,500 to 10,000 ppm) in inland seas and brine wells.
