Rocks and The Rock Cycle

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, involving the creation, breakdown, and reformation of rocks through geological processes.

How are igneous rocks formed?

Back

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

What is sediment?

Back

Sediment is rock material that has been broken down into smaller pieces or dissolved in water as a result of erosion.

What process turns sediment into sedimentary rock?

Back

Sediment becomes sedimentary rock through the processes of compaction and cementation.

Front

What is metamorphic rock?

Back

Metamorphic rock is rock that has been changed from its original form due to intense heat and pressure.

Front

What is the process of weathering?

Back

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

What is erosion?

Back

Erosion is the process by which rock and soil are removed from one location and transported to another by natural forces like water, wind, or ice.

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is the role of heat and pressure in the formation of metamorphic rocks?

Back

Heat and pressure cause changes in the mineral structure and composition of existing rocks, transforming them into metamorphic rocks.
