Unit 8 Review

Physical weathering is...

• It is the process where rocks are broken down by chemical reactions altering their composition.

• It is the process where rocks are broken down into smaller pieces while retaining their original chemical composition.

• It is the formation of new minerals from rock weathering.

• It is the gradual wearing away of rocks by water and wind.

Which of the following is an example of physical weathering?

• Frost Action

• Chemical Reaction

• Biological Growth

• Erosion

Chemical weathering is ...

• The process of physical abrasion of rocks.

• The process of breaking down rocks and minerals through chemical reactions.

• The process of rock formation.

• The process of erosion by water alone.

An example of carbonation in chemical weathering is:

• Limestone reacting with carbonic acid

• Granite disintegrating by freeze-thaw

• Oxidation of iron

• Mechanical breakdown by plant roots
