U2L4 The Rock Cycle

Front

What is the Rock Cycle?

Back

The Rock Cycle is the continuous process by which rocks are formed, broken down, and reformed through geological processes such as melting, cooling, erosion, and sedimentation.

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 by the cooling and solidification of magma or lava.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

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 the process of erosion?

Back

Erosion is the process by which rocks and soil are worn away and transported by natural forces such as wind or water.

Front

What is the role of heat in the Rock Cycle?

Back

Heat can cause rocks to melt into magma or change existing rocks into metamorphic rocks.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has reached the surface.

Front

What is recrystallization?

Back

Recrystallization is the process where minerals in a rock change their structure and form new crystals due to heat and pressure.

Front

What is a mineral?

Back

A mineral is a naturally occurring substance with a specific chemical composition and a crystalline structure.
