Rocks & Rock Cycle

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface that can form igneous rocks when it cools and solidifies.

Front

What is a metamorphic rock?

Back

A metamorphic rock is a type of rock that has been changed from its original form due to heat, pressure, or chemical processes.

Front

How are igneous rocks formed?

Back

Igneous rocks are formed through the process of melting and cooling of magma or lava.

Front

What type of rock is formed from the accumulation of sediments?

Back

Sedimentary rock is formed from the accumulation and compaction of sediments.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, including the processes of igneous, sedimentary, and metamorphic rock formation.

Front

What is sediment?

Back

Sediment refers to small particles of rock, minerals, and organic material that can accumulate and form sedimentary rocks.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks form from cooled magma or lava, while sedimentary rocks form from the accumulation and compaction of sediments.

Front

What role does heat play in the formation of metamorphic rocks?

Back

Heat can cause existing rocks to change their structure and composition, leading to the formation of metamorphic rocks.

Front

What is compaction in the context of sedimentary rock formation?

Back

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

Front

What is cementation?

Back

Cementation is the process by which dissolved minerals crystallize and bind sediment particles together to form sedimentary rock.
