Rock Cycle Flashcard

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 molten rock (magma or lava).

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form through the processes of weathering, erosion, deposition, compaction, and cementation of sediments.

Front

What is metamorphic rock?

Back

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

Front

What is the process of weathering?

Back

Weathering is the breaking down of rocks into smaller pieces due to environmental factors like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of rock and soil from one location to another, often caused by water, wind, or ice.

Front

What is deposition in the rock cycle?

Back

Deposition is the process where sediments are dropped and accumulate in new locations, forming sedimentary rocks.

Front

What is compaction?

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, forming solid rock.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has reached the surface.
