The Rock Cycle

How does igneous rock form?

• Through the cooling and hardening of magma or lava

• By the accumulation of sediments

• From the transformation of existing rocks under pressure

• By the erosion of existing rocks

Which type of sediment is likely to travel the farthest during erosion?

• Gravel

• Pebbles

• Clay particles

• Sand

What process involves the breakdown and movement of rocks?

• Crystallization

• Sedimentation

• Metamorphism

• Erosion

What is the result of partial melting of rocks?

• Formation of magma

• Creation of sedimentary layers

• Development of erosion patterns

• Formation of columnar basalts

What causes metamorphic rocks to form?

• Temperature and pressure changes

• Erosion and sedimentation

• Cooling of lava

• Volcanic activity
