Question

Which of the following statements accurately describes the formation of an intrusive igneous rock?

• A. It forms from the rapid cooling of lava on the Earth's surface, resulting in fine-grained crystals.
• B. It forms from the compaction and cementation of sediments over millions of years.
• C. It forms from the slow cooling of magma beneath the Earth's surface, allowing for the development of large crystals.
• D. It forms from the transformation of existing rocks due to high temperatures and pressures.

Hint:

Intrusive = slow cooling → large crystals.

Answer 1

The Correct Option is C

Intrusive igneous rocks like granite form deep inside Earth where magma cools slowly, creating large crystals.
