Rock Cycle Review

Front

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 igneous rocks?

Back

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

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles. Examples include sandstone and limestone.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed from the alteration of existing rocks (igneous, sedimentary, or other metamorphic rocks) due to heat, pressure, or chemically active fluids. Examples include schist and marble.

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process by which sediments settle out of a transporting medium (like water or air) and accumulate in a new location.

Front

What is compaction?

Back

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

Front

What is cementation?

Back

Cementation is the process by which dissolved minerals crystallize and bind sediment particles together, forming solid rock.

Front

How do igneous rocks transform into metamorphic rocks?

Back

Igneous rocks can transform into metamorphic rocks through exposure to high temperature and pressure, which alters their mineral structure.
