The Rock Cycle and Types of Rocks

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes how rocks change from one type to another over time through processes like melting, cooling, erosion, and compaction.

Front

What are the three main types of rocks?

Back

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

Front

How is igneous rock formed?

Back

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

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks cool slowly inside the Earth, while extrusive igneous rocks cool quickly on the Earth's surface.

Front

Where are intrusive rocks typically formed?

Back

Intrusive rocks are formed inside the Earth.

Front

Where are extrusive rocks typically formed?

Back

Extrusive rocks are formed outside the Earth.

Front

What process transforms sedimentary rock into igneous rock?

Back

Sedimentary rock transforms into igneous rock through melting and cooling.

Front

What is sedimentary rock primarily made of?

Back

Sedimentary rock is primarily made of particles from other rocks, minerals, and organic materials that have been compacted and cemented together.

Front

What is metamorphic rock?

Back

Metamorphic rock is 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 like wind, water, and temperature changes.
