Rocks in the Crust
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.
The distribution of rock types is a reflection of the rock cycle.
Sedimentary rocks are most common at the surface because they are
formed by processes that occur at the surface. Most igneous rocks
and metamorphic rocks are formed by processes that occur deeper
within Earth.
