This Cycle Rocks!
Earth's surface is constantly changing.
Gradual changes such as weathering
and erosion can change the look of the
surface over millions of years. More
sudden changes such as volcanic
eruptions and earthquakes can change
the surface in a matter of minutes.
The purpose of this site is to provide
students with an exploration of the
rock cycle, so that studetns can
investigate how rocks are formed and
how they can change.
