Rocks

A rock deep within the Earth experiences extreme temperature and pressure. After a long period of time it becomes which rock?

• Magma

• Igneous

• Metamorphic

• Sedimentary

Rocks and sediment change as they move through the rock cycle. Which change involves turning into melting?

• Lava to rock

• magma to lava

• rock to magma

• rock to sediment

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

Formed by heat and pressure

• Sedimentary
