Rocks and 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 processes like weathering, erosion, and heat.

Front

What are the three major types of rocks?

Back

Igneous, Metamorphic, Sedimentary.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form from the accumulation and compaction of sediments, which can include minerals, organic matter, and fragments of other rocks.

Front

What is metamorphic rock?

Back

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

Front

What is the difference between magma and lava?

Back

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

Front

What process turns metamorphic rock into sediment?

Back

Weathering is the process that breaks down metamorphic rock into sediments.

Front

What is igneous rock?

Back

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

Front

What is the role of heat in the rock cycle?

Back

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

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What is compaction in the context of sedimentary rocks?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume and forming sedimentary rock.
