Rock Transformations

Front

What are metamorphic rocks?

Back

Metamorphic rocks are rocks that have been changed from their original form due to high heat and pressure.

Front

Can igneous rocks form both below and above the Earth's surface?

Back

Yes, igneous rocks can be formed below the surface (intrusive) and on top of the Earth's surface (extrusive).

Front

What two processes are involved in the formation of sedimentary rocks?

Back

Sedimentary rocks are formed through compaction and cementation of sediments.

Front

What type of energy causes water to evaporate and create rain that weathers rocks?

Back

Energy from Earth's sun heats the water, causing evaporation and rain.

Front

Which types of rocks can be heated and cooled to form igneous rock?

Back

All three types of rocks: igneous, sedimentary, and metamorphic can be heated and cooled to form igneous rock.

Front

What is the rock cycle?

Back

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

Front

What is an igneous rock?

Back

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

Front

What is sedimentation?

Back

Sedimentation is the process by which sediments settle out of a fluid (like water) and accumulate.

Front

What is compaction in the context of sedimentary rock formation?

Back

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

Front

What is cementation in sedimentary rock formation?

Back

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