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 melting, cooling, erosion, and compaction.

Front

What are the three main types of rocks?

Back

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

Front

How does an igneous rock form?

Back

Igneous rocks form from the cooling and solidification of magma or lava.

Front

What is magma?

Back

Magma is molten rock that is found beneath the Earth's surface.

Front

What is lava?

Back

Lava is molten rock that has erupted onto the Earth's surface.

Front

What is sedimentary rock?

Back

Sedimentary rock forms from the accumulation and cementation of mineral and organic particles.

Front

What is metamorphic rock?

Back

Metamorphic rock forms when existing rocks are subjected to heat and pressure, causing physical and chemical changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What is weathering?

Back

Weathering is the breakdown of rocks into smaller pieces through physical, chemical, or biological processes.

Front

What is compaction in the context of sedimentary rocks?

Back

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