Igneous rocks are formed from

• magma and lava cooling off

• other rocks being changed by temperature and pressure

• pieces of rock and other solids getting cemented together over time

• other rocks breaking

Sedimentary rocks are formed from

• magma and lava cooling off

• other rocks being changed by temperature and pressure

• pieces of rock and other solids getting cemented together over time

What two intense things help form metamorphic rocks?

• Density

• Pressure

• Volume
