Rock Cycle, weathering and erosion

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 melting, cooling, erosion, and compaction.

How do animals contribute to weathering?

Back

Animals weather rocks by digging and burrowing into the soil, which breaks down the rocks.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces like wind, water, and biological activity.

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

What causes metamorphic rocks to form?

Back

Metamorphic rocks form from existing rocks that are changed by heat and pressure.

Front

What is an example of erosion caused by gravity?

Back

Landslides are an example of erosion caused by gravity.

How do igneous rocks form?

Back

Igneous rocks form from the cooling and solidification of molten rock (magma or lava).

Front

What is compaction in the context of sedimentary rocks?

Back

Compaction is the process where sediments are pressed together under pressure, leading to the formation of sedimentary rocks.

What is cementation?

Back

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