Weathering, Erosion, and Deposition Quiz

What is chemical weathering?

• The physical breaking down of rocks into smaller pieces

• The process by which rocks are broken down by chemical reactions

• The movement of sediment from one location to another

• The depositing of sediment in a new location

Which of the following is an example of physical weathering?

• Oxidation of minerals in rocks

• Dissolution of limestone by acid rain

• The cracking of rocks due to freezing and thawing of water

• The decomposition of rocks by living organisms

How does water cause erosion?

• By freezing and thawing

• By carrying rocks and sediment downstream

• By causing chemical reactions in rocks

• By depositing sediment in new locations

What role does water play in chemical weathering?

• It physically breaks rocks into smaller pieces

• It transports sediment to new locations

• It acts as a solvent in chemical reactions that break down rocks

• It freezes and expands in cracks in rocks

Which factor does NOT affect the rate of weathering?

• Rock type

• Climate

• The age of the rocks

• The presence of soil

What is the main difference between weathering and erosion?

• Weathering involves the movement of rocks, while erosion does not.

• Erosion involves the chemical breakdown of rocks, while weathering does not.

• Weathering is the breaking down of rocks, while erosion is the movement of the broken pieces.

• There is no difference; they are the same process.

Which of the following is a form of physical weathering?

• Hydrolysis

• Carbonation

• Exfoliation

• Oxidation

What is the primary cause of erosion by water?

• The chemical breakdown of minerals in rocks

• The movement of water in rivers, streams, and oceans

• The deposition of sediment in new locations

• The growth of plants in soil

Which of the following environments would most likely experience the fastest rate of chemical weathering?

• Hot and dry desert

• Cold and wet tundra

• Hot and humid rainforest

• Cold and dry polar region

What is the role of plant roots in physical weathering?

• They produce acid that chemically weathers rocks

• They transport water that chemically weathers rocks

• They grow into cracks in rocks and break them apart as they expand

• They cover rocks and protect them from weathering
