Unit 5: The 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.

Front

What is weathering?

Back

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

Front

What is erosion?

Back

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

Front

What is sediment?

Back

Sediment refers to small particles of rock, minerals, and organic material that are transported and deposited by erosion.

Front

What is compaction?

Back

Compaction is the process by which sediments are pressed together under pressure, reducing their volume.

Front

What is cementation?

Back

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

Front

What are igneous rocks?

Back

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

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of sediments, often in layers.

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 the role of heat and pressure in the rock cycle?

Back

Heat and pressure can transform sedimentary and igneous rocks into metamorphic rocks.
