Which mineral is known for its ability to refract light?
-
Diamond
-
Quartz
-
Topaz
-
Fluorite
A
Correct answer
Explanation

Which of the following is NOT a common method of mineral mining?
-
Surface mining
-
Underground mining
-
Placer mining
-
Fracking
D
Correct answer
Explanation
Fracking is a method used to extract natural gas and oil from underground, not minerals.
Which mineral is commonly mined using the open-pit mining method?
-
Gold
-
Copper
-
Coal
-
Diamonds
C
Correct answer
Explanation
Open-pit mining is commonly used to extract coal, as it is found near the surface and can be easily accessed.

What is the primary source of data for the National Mineral Inventory (NMI) in India?
-
Satellite imagery
-
Topographic maps
-
Field surveys
-
Mineral exploration data
D
Correct answer
Explanation
The primary source of data for the National Mineral Inventory (NMI) in India is mineral exploration data. Mineral exploration data includes information about the location, size, and quality of mineral deposits.
Which of the following is NOT a mineral resource?
C
Correct answer
Explanation
Water is a renewable resource and not considered a mineral resource, unlike gold, coal, and copper, which are finite and extracted from the Earth's crust.
What is the term used to describe the natural accumulation of valuable minerals in the Earth's crust?
-
Ore
-
Deposit
-
Reserve
-
Resource
B
Correct answer
Explanation
A mineral deposit is a natural concentration of valuable minerals in the Earth's crust that is economically viable to extract. It is formed through geological processes such as magmatism, hydrothermal activity, and weathering.
Which mineral is commonly used in the production of aluminum?
-
Bauxite
-
Hematite
-
Magnetite
-
Galena
A
Correct answer
Explanation
Bauxite is the primary ore of aluminum. It is a sedimentary rock composed of aluminum oxides and hydroxides. The aluminum in bauxite is extracted through a process called the Bayer process, which involves dissolving the ore in a caustic soda solution.
