Rock It Out

The Three Types of Rocks

There are three types of rocks on the Earth's surface. The three types are igneous, sedimentary, and metamorphic.

The first type of rock is Igneous. Igneous is made by hot magma cooling. Igneous magma takes along time to cool into igneous.

The second type of rock is Sedimentary is made by small pieces of sediment and pressure pushing it together. They harden over time.

The last type of rock is metamorphic. Metamorphic rock is made by Igneous or sedimentary being pressured and burned.
