Weathering Processes Quiz

What is the primary difference between physical and chemical weathering?

• Physical weathering alters the physical form without changing chemical composition.

• Chemical weathering only changes the size and shape of rocks.

• Chemical weathering does not involve any change in the material.

• Physical weathering changes the chemical composition of rocks.

Which of the following is an example of physical weathering caused by abrasion?

• A rock dissolving in acid rain.

• Tree roots cracking a sidewalk.

• Sediment smoothing the edges of a river rock.

• Limestone reacting with carbon dioxide.

How do tree roots contribute to physical weathering?

• By reacting with minerals to form new compounds.

• By smoothing rock surfaces in rivers.

• By pushing up sidewalks and cracking rocks as they grow.

• By dissolving rocks with acid.

What happens during the process of dissolution in chemical weathering?

• Rocks are physically broken into smaller pieces.

• Rocks are cracked by growing tree roots.

• Rocks are dissolved by water or acid.

• Rocks are smoothed by sediment.

Which scenario is an example of carbonation in chemical weathering?

• A tree root cracking a rock.

• Limestone being affected by acid rain.

• A rock expanding and contracting due to temperature changes.

• A rock being smoothed by river sediment.
