Question

The rock which is made up of molten magma is

• A. igneous
• B. sedimentary
• C. metamorphic
• D. none of these

Answer 1

The correct option is A

igneous

Explanation for the correct option:

(a) Igneous

• One of the three primary rock types, along with sedimentary and metamorphic rocks, is igneous rock, which is derived from the Latin word ignis, which means "fire."
• When lava or magma cools and solidifies, igneous rock is created.
• Hence this option is correct

Explanation for the incorrect options:

(b) Sedimentary

• The intense compression and hardness of the sediment particles that are deposited by water, wind, and other forces causes sedimentary rocks to be created from sediments.
• Minerals and organic substances accumulate as sediment and go through sedimentation.
• Thus, this option is incorrect.

(c ) Metamorphic

• These rocks change, either because to intense heat, high pressure, or exposure to hot liquid rich in minerals, which changes the composition of the minerals and changes the existing rock into a new type of rock.
• A metamorphic rock can be created by either one of these three elements, or by combining them.
• Thus, this option is incorrect.

(d) none of these

• When lava or magma cools and solidifies, igneous rock is created.
• Hence this option is not applicable.
• Thus, this option is incorrect.

Hence the correct option is (a) Igneous
