Igneous rock.

Front

What happens in the rock cycle?

Back

As sedimentary rocks are buried deep below other rocks, they are changed by heat and pressure, eventually return to the surface, and are weathered again.

Front

What is the texture of intrusive rocks?

Back

Coarse-grained texture due to slow cooling.

Front

What is the texture of extrusive rocks?

Back

Fine-grained texture due to rapid cooling.

Front

What is erosion?

Back

The process of moving weathered rock and soil from one location to another.
