What are the three main types of rocks?

• Crystals, Sediments, Lava

• Igneous, Sedimentary, Metamorphic

• Diamonds, Rubies, Sapphires

• Marble, Granite, Slate

How is igneous rock formed?

• By cooling and solidifying of magma or lava

• By pressure and heat inside the Earth

• By accumulation and cementation of mineral grains

• By being exposed to the atmosphere

What is the process called when sedimentary rock is formed from sediments?

• Melting

• Erosion

• Compaction and Cementation

• Metamorphism

Which type of rock could eventually become a metamorphic rock?

• Only Igneous

• Only Sedimentary

• Both Igneous and Sedimentary

• Igneous, Sedimentary, and Metamorphic

What drives the rock cycle?

• The Sun

• Gravity

• Earth's internal heat

• Water
