Rocks and the Rock Cycle

Front

What is the Rock Cycle?

Back

The Rock Cycle is the continuous process of rock changing from one type to another, including igneous, sedimentary, and metamorphic rocks.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of molten rock (magma or lava).

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of sediments, which can include minerals, organic material, and fragments of other rocks.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed when existing rocks are changed by heat and pressure.

Front

What is weathering?

Back

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

Front

What is erosion?

Back

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

Front

What are sediments?

Back

Sediments are small pieces of rock, minerals, or organic material that have been broken down by weathering.

Front

What is the role of heat in the formation of metamorphic rocks?

Back

Heat causes changes in the mineral structure of existing rocks, leading to the formation of metamorphic rocks.

Front

What is the role of pressure in the formation of metamorphic rocks?

Back

Pressure can cause rocks to become denser and change their structure, contributing to the formation of metamorphic rocks.

Front

Can sedimentary rocks become igneous rocks?

Back

Yes, sedimentary rocks can become igneous rocks through the process of melting and cooling.
