Granite is a _____ rock.

Igneous

Metamorphic

Sedimentary

None of these

Correct Answer : Igneous

Consider how granite changes form. Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss.
