Types of Rock

There are three kinds of rock:

Igneous rocks - come from inside the earth...look here for a cool animated site.

Sedimentary rocks are made by particles of rock (or sand) being dropped or deposited in layers.

Metamorphic rocks are made by changing one of the other types of rock.

We call the process of making and changing rocks The Rock Cycle. Look here too.
