Rock Cycle

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various stages: igneous, sedimentary, and metamorphic.

Front

What are igneous rocks?

Back

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

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed from existing rocks that have been changed by heat, pressure, or chemically.

Front

How are fossils related to sedimentary rocks?

Back

Fossils are often found in sedimentary rocks because these rocks are formed from the remains of once-living organisms.

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 process by which soil and rock are removed from one location and transported to another by natural forces.

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 in the rock cycle?

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.
