Question

how are intrusive and extrusive rocks formed answer in one sentence​

Answer 1

Answer:

Hello...

Explanation:

The two main categories of igneous rocks are extrusive and intrusive.

Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground.

Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.

Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals. Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals.
