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 geological processes, including igneous, sedimentary, and metamorphic rocks.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of magma or lava.

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of sediments, which can include minerals, organic matter, and fragments of other rocks.

Front

What are metamorphic rocks?

Back

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

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces such as wind, water, and temperature changes.

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 water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations after being transported by erosion.

Front

What is the role of heat in the rock cycle?

Back

Heat can cause rocks to melt into magma or change existing rocks into metamorphic rocks.

Front

What is the role of pressure in the rock cycle?

Back

Pressure can cause sedimentary rocks to become metamorphic rocks by altering their structure and composition.

Front

How does sediment become sedimentary rock?

Back

Sediment becomes sedimentary rock through processes of compaction and cementation.
