Where Do Plutonic Igneous Rocks Form?

Plutonic rocks are rocks formed when magma cools and solidifies below the earth's surface. Plutonic rocks are also known as 'intrusive igneous rocks' because they form when magma squeezes into cracks and crevices, as if it is an 'intruder' who is invading the rocks.

Where are plutonic rocks found?

Intrusive rock, also called plutonic rock, igneous rock formed from magma forced into older rocks at depths within the Earth's crust, which then slowly solidifies below the Earth's surface, though it may later be exposed by erosion.

How are plutonic igneous rocks formed?

Plutonic rocks are formed when magma cools and solidifies underground. Volcanic rocks are formed from lava that flows on the surface of the Earth and other planets and then cools and solidifies. The texture of an igneous rock depends on the size of the crystals in the rock.
