Earth's crust consists of solid rock that consists of both dry land and the ocean floor and forms Earth's outer skin. If you really want to get technical, it consists of oxygen, silicon, aluminum, calcium, iron, sodium, potassium, and magnesium.

The crust of the Earth is composed of igneous, metamorphic, and sedimentary rocks.
