Metamorphic rocks are pre-existing rocks that are transformed by these two things.

Heat and pressure

Sedimentary rocks are created by these two phenomenon.

Weathering, erosion, and/or deposition

100

A type of weathering where rocks break apart, but do not change their chemical structure.

Physical weathering

These are rocks on the Earth's surface.
What are extrusive igneous rocks?
200

A type of weathering where living organisms change the surface of a rock.

Biological weathering

The loosening, removal, and transport of weathered rocks.

Erosion

300

A type of erosion where ice freezing and thawing can break apart a rock.

This creates small bubbles inside of igneous rocks.

Gas

After sediments are transported somewhere, they are then laid down in layers in a process called...
Deposition.
400

A type of erosion where rocks can be oxidized or dissolved.

Chemical weathering

500

Before igneous rocks become solid, they are made of liquid magma in this part of the Earth.

The mantle
