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, driven by geological processes such as weathering, erosion, and heat.

What role does water play in the rock cycle?

Back

Water participates in weathering, erosion, and the transportation of sediment.

Front

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 are igneous rocks?

Back

Igneous rocks are formed from the 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 sediment, which can include fragments of other rocks, minerals, and organic material. Examples include sandstone and limestone.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed from existing rocks that are transformed by heat, pressure, or chemically active fluids. Examples include schist and marble.

Front

How do sedimentary rocks form?

Back

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

Front

What is lithification?

Back

Lithification is the process of turning loose sediment into solid rock through compaction and cementation.

Front

What is the difference between magma and lava?

Back

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