Answer:

Igneous rocks come from inside the Earth. Igneous rocks include lavas that form during volcanic eruptions, but also include magma that cools down and becomes solid before reaching the surface. Igneous rocks

are formed by the cooling and solidifying of molten materials. Igneous rocks can form beneath the Earth's surface, or at its surface, as lava. Igneous rocks can be divided into four categories based on their chemical composition: felsic, intermediate, mafic, and ultramafic.
