Rock Cycle

The Rock Cycle is the natural process that explains how rocks change from one type to another over time.

There are 3 main types of rocks:

1. Igneous Rock – formed from cooled lava or magma
2. Sedimentary Rock – formed from layers of sand, mud, and tiny rock pieces
3. Metamorphic Rock – formed when rocks change because of heat and pressure
