Granite is an example of
- ASedimentary rock
- BMetamorphic rock
- CIgneous RockCorrect
- DAqueous rock
Solution
Concept
Geological classification of rocks
Formula
NONE
Step-by-step solution
1. Igneous rocks are formed by the cooling and solidification of molten magma or lava. 2. Granite is formed deep beneath the Earth surface by slow cooling of magma. 3. Therefore, granite is an example of an igneous rock. Answer: C
Explanation
Granite is formed from the slow crystallization of magma beneath the surface of the Earth, making it an intrusive igneous rock. Because it cools underground over an extended period, it develops coarse and visible mineral grains. Therefore, granite is categorized under igneous rocks.
Why the other options are wrong
A) Sedimentary rocks are formed by the deposition and consolidation of sediments. B) Metamorphic rocks are formed by the alteration of pre-existing rocks under heat and pressure. D) Aqueous rocks are sedimentary rocks deposited by water.
Shortcut
Granite is Igneous: remember "GI" (Granite = Igneous rock).
Common mistake
Confusing granite with metamorphic or sedimentary rock due to its crystalline structure.
Correct answer: C) Igneous Rock
