What type of weathering involves the physical breaking down of rocks into smaller pieces without changing the chemical composition?

• Chemical weathering

• Physical weathering

• Biological weathering

• Mechanical weathering

What is the main difference between weathering and erosion?

• Weathering involves movement, while erosion does not.

• Erosion involves movement, while weathering does not.

• Weathering can only be caused by water, while erosion can be caused by wind, water, and ice.

• Erosion can only happen with rocks, while weathering can happen with rocks and minerals.

Which of the following is an example of chemical weathering?

• Frost wedging

• Acid rain breaking down rock surfaces

• Tree roots breaking through rock

• Wind blowing sand against a rock face

What role does water play in physical weathering?

• It dissolves rocks completely.

• It carries rocks away to different locations.

• It freezes in cracks of rocks and expands, causing the rock to break.

• It chemically reacts with rocks to form new minerals.

Which of the following rock formations is most likely to be created by deposition?

• A mountain range

• A sand dune

• A volcanic cone

• A granite outcrop

How does wind contribute to erosion?

• By depositing large amounts of sediment in one area

• By carrying small particles away from their original location

• By causing chemical reactions with rocks

• By freezing and thawing in rock cracks
