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

How are igneous rocks formed?

Back

Igneous rocks are formed when magma (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 movement of sediments from one location to another, often caused by water, wind, or ice.

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and cementation 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 cementation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together.

Front

What is melting in the rock cycle?

Back

Melting is the process where solid rocks turn into magma due to extreme heat.

Front

What is the role of heat and pressure in the rock cycle?

Back

Heat and pressure can transform existing rocks into metamorphic rocks.

Front

What is an example of an igneous rock?

Back

Examples of igneous rocks include basalt, granite, and obsidian.
