Question

why do you think most of earth's igneous and metamorphic rocks are below earth's surface?

Answer 1

Igneous, sedimentary, and metamorphic rocks are all found in Earth's crust. But these rock types are not evenly distributed. Most of Earth's crust—95 percent of it—consists of igneous rock and metamorphic rock. Sedimentary rock, which forms a thin covering on Earth's surface, makes up only 5 percent of the crust.
