Understanding the Rock Cycle

What happens to rock when it is exposed to intense heat?

• It evaporates.

• It turns into soil.

• It melts to form magma.

• It becomes sedimentary rock.

Which process involves the transportation of rock fragments?

• Crystallization

• Erosion

• Solidification

• Weathering

How do sedimentary rocks form over time?

• Through crystallization of minerals

• Through the cooling of lava

• By the compression and compaction of sediments

• By melting under high heat

What causes metamorphic rocks to form?

• Erosion by wind and water

• Deposition of sediments

• Exposure to high heat and pressure

• Cooling of magma

What does the rock cycle demonstrate about rocks?

• Rocks never change once formed.

• Rocks are only formed from lava.

• Rocks can transform into different types over millions of years.

• Rocks are not affected by heat and pressure.
