Q1.
Which mineral group is the primary constituent in rock-forming minerals?
Oxides
Silicates
Carbonates
Sulfides
Show answer
Answer: B. Silicates
Silicates (including feldspar, mica etc.) are the primary rock-forming minerals, followed by oxides and carbonates.
Q2.
What are rocks defined as according to geological terms?
Soft mineral deposits
Hard deposits of mineral substances forming Earth's surface
Liquid mineral formations
Gaseous mineral compounds
Show answer
Answer: B. Hard deposits of mineral substances forming Earth's surface
Rocks are defined as hard deposits of mineral substances that form the Earth's surface structure.
Q3.
Which of the following is an example of carbonate minerals mentioned in rock formation?
Quartz
Hematite
Calcite
Magnetite
Show answer
Answer: C. Calcite
Calcite and dolomite are examples of carbonate minerals, while quartz, hematite, and magnetite are oxide minerals.
Q4.
In the classification of rock-forming minerals, what comes after silicates in order of importance?
Carbonates
Oxides
Sulfates
Halides
Show answer
Answer: B. Oxides
The order of importance in rock-forming minerals is: Silicates first, followed by oxides, then carbonates.
Q5.
Which type of rocks are formed from the cooling and solidification of magma?
Sedimentary rocks
Metamorphic rocks
Igneous rocks
Organic rocks
Show answer
Answer: C. Igneous rocks
Igneous rocks are formed from the cooling and solidification of molten magma or lava.

Feldspar
Mica
Quartz
Calcite
Show answer
Answer: C. Quartz
Quartz is an oxide mineral (silicon dioxide), while feldspar and mica are silicate minerals, and calcite is a carbonate mineral.
Q7.
What is the process called when existing rocks are transformed into new rocks due to heat and pressure?
Weathering
Erosion
Metamorphism
Sedimentation
Show answer
Answer: C. Metamorphism
Metamorphism is the process by which existing rocks are transformed into metamorphic rocks due to heat, pressure, or chemical changes.
Q8.
Which mineral is mentioned as an example of silicate minerals in rock formation?
Hematite
Dolomite
Feldspar
Magnetite
Show answer
Answer: C. Feldspar
Feldspar and mica are mentioned as examples of silicate minerals, which are the primary rock-forming minerals.
Q9.
What type of deposits form the building blocks of rocks according to the definition?
Soft organic deposits
Hard mineral deposits
Liquid deposits
Gaseous deposits
Show answer
Answer: B. Hard mineral deposits
Rocks are formed from hard deposits of mineral substances that constitute the Earth's surface structure.
Q10.
Among the following, which represents the correct sequence of importance in rock-forming mineral groups?
Oxides → Silicates → Carbonates
Carbonates → Oxides → Silicates
Silicates → Oxides → Carbonates
Silicates → Carbonates → Oxides
Show answer
Answer: C. Silicates → Oxides → Carbonates
The correct order of importance in rock-forming minerals is: Silicates (primary), followed by Oxides, then Carbonates.
