Rock Transformations

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed from the accumulation and compaction of mineral and organic particles, often found in layers.

Front

How is sedimentary rock formed?

Back

Sediment is moved to an area near water. Over time, the sediment is compacted and cemented together to form sedimentary rock.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process where rocks are formed, broken down, and reformed through various geological processes.

Front

What are igneous rocks?

Back

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

Front

Can igneous rocks form below the Earth's surface?

Back

Yes, igneous rocks can be formed below the surface (intrusive) and on top of the Earth's surface (extrusive).

Front

What is compaction in the context of sedimentary rocks?

Back

Compaction is the process where sediments are buried and pressed together under the weight of overlying materials.

Front

What is cementation?

Back

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

Front

What are the two main energy sources in the rock cycle?

Back

The two main energy sources involved in the rock cycle are energy from the Earth's interior (core) and energy from the sun.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that are changed by heat, pressure, or chemically active fluids.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.
