• Magma

• Igneous

• Metamorphic

• Sedimentary

What must happen to a metamorphic rock before it becomes a sedimentary rock rock?

• It must be broken down into sediment

• It must be melted into magma

• Its minerals must dissolve in water

• It must be exposed to high temperature and pressure

How do sedimentary rocks form?

• Lava or magma cools and hardens

• Sand, mud and pebbles settles into layers and get squeezed together.

• Extreme heat or pressure turn old rocks into new rocks

• Under trampolines
