Rock Cycle

Front

What is the rock cycle?

Back

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

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How are sedimentary rocks formed?

Back

Sedimentary rocks are formed through the processes of compaction and cementing of sediments.

Front

What process exposes buried rocks at the Earth's surface?

Back

Weathering and erosion are responsible for exposing buried rocks at the Earth's surface.

Front

What type of rock is formed when magma cools and hardens?

Back

Igneous rock is formed when magma cools and hardens.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that are changed by heat and pressure.

Front

What role does weathering play in the rock cycle?

Back

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

Front

What is the process of cementation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together to form sedimentary rock.

Front

What happens to sedimentary rock under extreme heat and pressure?

Back

Sedimentary rock can transform into metamorphic rock under extreme heat and pressure.

Front

What is an example of an igneous rock?

Back

Granite is an example of an igneous rock.
