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 are the three main types of rocks?

Back

Igneous, sedimentary, and metamorphic.

Front

What is igneous rock?

Back

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

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from compressed or cemented layers of sediment.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that are changed by heat, pressure, or chemical processes.

Front

How does igneous rock form?

Back

Igneous rock forms when magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive).

Front

What processes lead to the formation of sedimentary rock?

Back

Sedimentary rock forms through the processes of weathering, erosion, deposition, compaction, and cementation of sediments.

Front

What role do heat and pressure play in the rock cycle?

Back

Heat and pressure can transform existing rocks into metamorphic rocks.

Front

What are minerals?

Back

Minerals are naturally occurring substances that are made of crystals and have a specific chemical composition and geometric shape.

Front

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.
