How and where are igneous rocks formed?

Answer 1

Igneous rocks are formed on and below the surface of the Earth when lava or magma cools enough to crystallize.

Answer 2

Igneous rocks are formed when molten magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). Intrusive igneous rocks are formed from magma that cools slowly underground, while extrusive igneous rocks are formed from lava that cools quickly on the surface.

Answer 3

Igneous rocks are formed in volcanos. They form from the molten lava when it hardens and the ash from the volcano.

Answer 4

It's when magma from under or above the earths surface,(lava or magma), cools and turns solid.
