The Rock Cycle

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 various geological processes.

Front

What are the three main types of rocks?

Back

Igneous, sedimentary, and metamorphic.

Front

How are igneous rocks formed?

Back

Igneous rocks are formed when magma (or lava) cools and solidifies, creating crystals.

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 process by which sediments and rocks are moved from one location to another, often by water, wind, or ice.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, often transported by water or wind.

Front

What process turns sediment into sedimentary rock?

Back

Compaction and cementation.

Front

What is metamorphic rock?

Back

Metamorphic rock is rock that has been changed from its original form due to heat, pressure, or chemically active fluids.

Front

What is melting in the rock cycle?

Back

Melting is the process that turns solid rock into magma, which can then cool to form igneous rock.

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 Earth's surface.
