Which type of rocks is formed at relatively high temperatures and by crystallization of solids?

Correct option is D

The correct answer is: (d) Igneous rocks
Explanation:
· Igneous rocks are formed by the cooling and solidification of molten magma from the Earth’s interior, often at high temperatures.
Information Booster:
· Two types: Intrusive (granite) and extrusive (basalt).
· First rock type in the rock cycle.
· Major component of Earth’s crust.
· Crystalline in structure.
· Known as primary rocks.
· Examples: Granite, Basalt, Diorite.
Additional Information:
· Metamorphic – Formed from existing rocks under heat & pressure.
· Volcanic – A subset of igneous rocks, but not complete category.
· Sedimentary – Formed by deposition and compression of sediments.
