Back

The rock cycle is a continuous process that describes how rocks change from one type to another over time through processes like melting, cooling, erosion, and compaction.

True

Front

How are sedimentary rocks formed?

Front

What is the difference between igneous and sedimentary rocks?

Front

What process turns sediment into sedimentary rock?

Back

Compaction and cementation.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that are changed by heat, pressure, or chemically.

Front

What is the role of weathering in the rock cycle?

Back

Weathering breaks down rocks into smaller particles, which can then be transported and deposited to form sedimentary rocks.
