• The word igneous means “fire”. This will help us remember how they are formed.

• These are rocks that are formed from magma that has cooled and hardened.

Volcano erupts and lava spills out onto the earth.

Lava cools and hardens. Igneous Rocks are formed.

• Look at the word sedimentary. What word do you see in it?

• If you said sediment then you are right!• Sediments are small pieces of dirt, sand,

mud and clay.• Sedimentary rocks are formed when

these sediments pile up on each other for thousands or even millions of years. The pressure from the sediments above turns the material on the bottom into sedimentary rocks.

• “Meta” and “morph” means a change in form• Metamorphic rocks are made from sedimentary and

igneous rocks.• These rocks are formed when heat and pressure are

added to igneous or sedimentary rocks. This usually happens when mountains are made.

The Rock Cycle

These are made from heat and

pressure of other types of

rocks.

The pressure of many layers of sediments on

top of one another creates

this rock.

This rock is formed when lava from a volcano cools and hardens.
