8th Grade Rock Cycle

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, driven by geological processes such as weathering, erosion, and tectonic activity.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

What process involves the breaking down of rocks by wind, water, and ice?

Back

Weathering.

Front

What is compaction in the context of the rock cycle?

Back

Compaction is the process where sediments are pressed together under pressure, leading to the formation of sedimentary rocks.

Front

What is cementation?

Back

Cementation is the process by which dissolved minerals crystallize and glue particles of sediment together, forming sedimentary rock.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks due to heat, pressure, or chemically active fluids.

Front

What role do tectonic plates play in the rock cycle?

Back

Tectonic plates create heat and pressure through their movement, which can lead to the formation of metamorphic rocks and volcanic activity.

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

Can a rock type follow multiple pathways in the rock cycle?

Back

Yes, a rock type can follow multiple pathways in the rock cycle, allowing for various transformations.

Front

What is the significance of heat and pressure in the rock cycle?

Back

Heat and pressure are crucial in the formation of metamorphic rocks and can also lead to melting, forming igneous rocks.
