Rocks and 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 melting, cooling, erosion, and compaction.

How are igneous rocks formed?

Back

Igneous rocks are formed from the cooling and solidification of molten 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 chemical processes.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces due to exposure to natural elements like wind, water, and temperature changes.

What is erosion?

Back

Erosion is the process by which weathered rock and soil are moved from one location to another by natural forces such as water, wind, or ice.

Can sedimentary rocks become igneous rocks?

Back

Yes, sedimentary rocks can become igneous rocks if they are subjected to extreme heat and pressure, causing them to melt and then cool.

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 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.
