Rocks are classified in a variety of ways, but one way they are classified is by the composition.
There are three basic rock types: igneous, sedimentary, and metamorphic.
However, there’s also another classification method that you may not be aware of- mineral type.
In this blog post we’ll cover both of these classifications methods to help you better understand how rocks themselves can be classified!
Igneous rocks are a type of rock that come from molten material, such as magma.

Sedimentary rocks form when deposits made on top of one another which creates layers over time.
