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 various geological processes.

Front

What is melting in the context of the Rock Cycle?

Back

Melting is the process where solid rock is heated to a high temperature, turning it into magma or lava.

Front

What role does heat and pressure play in the formation of metamorphic rocks?

Back

Heat and pressure cause existing rocks to change their structure and composition, resulting in the formation of metamorphic rocks.

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations after being transported by erosion.

Front

What is compaction?

Back

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

Front

What is cementation?

Back

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

Front

What is cooling and crystallization?

Back

Cooling and crystallization is the process where molten rock (magma or lava) cools and solidifies to form igneous rock.

Front

What is the difference between magma and lava?

Back

Magma is molten rock found beneath the Earth's surface, while lava is magma that has reached the Earth's surface.
