Examples of Types of Weathering

Any process that weakens and breaks apart rocks without changing the chemical makeup of the rock.

• physical weathering

• chemical weathering

• oxidation

• chemical reaction

Any process that weakens and breaks apart rock by chemically changing them into different substances.

• physical weathering

• chemical weathering

• root pry

• ice wedging

As roots of plants grown, they cause rocks to split.

• ice wedging

• root pry

• chemical weathering

• exfoliation

As water freezes and expands, then thaws, forces on rocks continuously change, causing them stress. This weakens the rock over time.

• abrasion

• ice wedging

• acid rain

• oxidation

What is an example of chemical weathering?

• A rock splitting because of a tree root growing in it

• A rock being smoothed by a river

• A rock changing color due to acid rain

• A rock getting buried under soil

Rainwater has a pH below 7 due to the presence of carbon dioxide. This tends to break down rocks, especially those made of calcite, limestone, and marble. This is an example of

• carbonic acid action

• oxidative action

• abrasion

• hydration
