Rocks and the 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 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 sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles, often containing fossils.

Front

What is metamorphic rock?

Back

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

Front

What processes can change sedimentary rock into metamorphic rock?

Back

Sedimentary rock can change into metamorphic rock through heat and pressure.

Front

What is the process of melting in the rock cycle?

Back

Melting is the process where solid rock turns into magma due to high temperatures.

Front

What is the process of cooling in the rock cycle?

Back

Cooling is the process where magma or lava loses heat and solidifies into igneous rock.

Front

What is compaction in the formation of sedimentary rocks?

Back

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

Front

What is cementation in the formation of sedimentary rocks?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together.
