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 melting, cooling, erosion, and compaction.

What are the three main types of rocks?

Back

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

Front

What is igneous rock?

Back

Igneous rock is formed from the cooling and solidification of magma or lava.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks are changed by heat, pressure, or chemically active fluids.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical or chemical means.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces such as wind or water.

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under their own weight, reducing their volume.

What is cementation?

Back

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

Front

What is the role of heat and pressure in the rock cycle?

Back

Heat and pressure can transform existing rocks into metamorphic rocks by altering their mineral structure.
