Answer 1

Answer:

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.

Answer 2

The two main categories, of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the earth from larva, which is magma that has emerged from underground. Intrusive rocks are found from magma that cools and solidifies within the crust of the planet.
