Understanding the Rock Cycle

What is a key characteristic of the rock cycle?

• It only involves igneous rocks.

• It is not a cycle.

• It can proceed in any order.

• It follows a strict order.

Which type of rock is formed from cooled magma?

• Sedimentary

• Metamorphic

• Igneous

• Foliated

What process involves the combination of compaction and cementation?

• Lithification

• Weathering

• Metamorphism

• Erosion

What causes the squiggly lines in metamorphic rocks?

• Extreme pressure

• Cooling magma

• Erosion

• Cementation

What happens to rocks under extreme heat and pressure but not enough to melt them?

• They become igneous rocks.

• They become sedimentary rocks.

• They become metamorphic rocks.

• They become foliated rocks.
