Which of these is a metallic mineral?
- A. Mica
- B. Limestone
- C. Iron ore
- D. Coal
Answer: C. Iron ore
Iron ore is a metallic mineral because it contains metal. Mica and limestone are non-metallic minerals, while coal is an energy resource.

Which is the finest quality of iron ore mentioned in NCERT?
- A. Lignite
- B. Magnetite
- C. Bauxite
- D. Mica
Answer: B. Magnetite
Magnetite is the finest iron ore with a very high iron content of up to 70 percent. It has excellent magnetic qualities.

Bauxite is the ore of which metal?
- A. Copper
- B. Aluminium
- C. Manganese
- D. Iron
Answer: B. Aluminium
Bauxite is the main ore from which aluminium is obtained. It is formed by decomposition of rocks rich in aluminium silicates.

In igneous and metamorphic rocks, minerals generally occur in:
- A. Beds and layers
- B. Veins and lodes
- C. Placer deposits only
- D. Ocean water only
Answer: B. Veins and lodes
In igneous and metamorphic rocks, minerals occur in cracks, crevices, faults or joints called veins and lodes. Smaller occurrences are called veins and larger ones are called lodes.

Which of the following pairs is correctly matched?
- A. Mica - Ferrous mineral
- B. Coal - Metallic mineral
- C. Copper - Non-ferrous mineral
- D. Limestone - Fossil fuel
Answer: C. Copper - Non-ferrous mineral
Copper is a non-ferrous metallic mineral because it does not contain iron. Mica and limestone are non-metallic minerals, while coal is an energy mineral.

Why is the use of solar energy especially suitable in rural and remote areas of India?
- A. It requires large coal mines nearby
- B. It reduces dependence on firewood and dung cakes
- C. It can be generated only near petroleum fields
- D. It increases the use of non-renewable fuels
Answer: B. It reduces dependence on firewood and dung cakes
Solar energy can reduce the dependence of rural households on firewood and dung cakes. This also helps conserve forests and organic manure.

Which statement correctly explains why minerals need to be conserved?
- A. Minerals are renewable and can be quickly replaced
- B. Mineral formation is slow, and their extraction is often wasteful
- C. Minerals are found equally in all parts of India
- D. Minerals are not required in modern industries
Answer: B. Mineral formation is slow, and their extraction is often wasteful
Minerals are finite and take millions of years to form. Mining and processing also involve losses, so planned and sustainable use is necessary.

Consider the statements: I. Magnetite is the finest iron ore. II. Hematite has iron content up to 70 percent and has excellent magnetic qualities. Which is correct?
- A. Only I
- B. Only II
- C. Both I and II
- D. Neither I nor II
Answer: A. Only I
Magnetite is the finest iron ore and has up to 70 percent iron with excellent magnetic qualities. Hematite is an important industrial iron ore but has slightly lower iron content.

Which sequence correctly arranges coal types from lowest to highest carbon content?
- A. Anthracite, bituminous, lignite, peat
- B. Peat, lignite, bituminous, anthracite
- C. Lignite, peat, anthracite, bituminous
- D. Bituminous, lignite, peat, anthracite
Answer: B. Peat, lignite, bituminous, anthracite
Coal quality improves with higher carbon content. The correct order is peat, lignite, bituminous and anthracite.
