Rock Cycle

What is the Rock Cycle?

Back

The Rock Cycle is a continuous process that describes the transformation of rocks through various geological processes, including igneous, sedimentary, and metamorphic formations.

Front

What are the three main types of rocks?

Back

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

Front

How are igneous rocks formed?

Back

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

Front

What is sedimentation?

Back

Sedimentation is the process by which particles settle out of a fluid, leading to the formation of sedimentary rocks.

Front

What is compaction in the context of sedimentary rocks?

Back

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

Front

What is cementation?

Back

Cementation is the process where dissolved minerals precipitate from water and fill the spaces between sediment particles, binding them together to form sedimentary rock.

Front

What conditions lead to the formation of metamorphic rocks?

Back

Metamorphic rocks are formed under high pressure and temperature conditions, which alter the mineral composition and structure of existing rocks.

Front

What is an example of a sedimentary rock?

Back

An example of a sedimentary rock is sandstone, which is formed from sand particles that have been compacted and cemented together.

Front

What is an example of a metamorphic rock?

Back

An example of a metamorphic rock is schist, which is formed from the metamorphism of shale.

Front

What is the role of weathering in the rock cycle?

Back

Weathering is the process that breaks down rocks into smaller particles, which can then be transported and deposited to form sedimentary rocks.
