Weathering and Coastal Processes Quiz

What is freeze-thaw weathering?

• A process where water enters cracks in rocks, freezes, and expands.

• A process where plants grow on rocks.

• A process where rocks are dissolved by acid rain.

• A process where animals burrow into rocks.

Which type of weathering involves plant roots?

• Chemical weathering

• Biological weathering

• Freeze-thaw weathering

• Erosion

What happens to water in cracks during freeze-thaw weathering when temperatures drop?

• It remains the same.

• It turns into acid.

• It evaporates.

• It freezes and expands.

Which type of rock is most affected by chemical weathering?

• Sandstone

• Basalt

• Granite

• Limestone

What is the main cause of chemical weathering?

• Wind

• Weak acids in rainwater and seawater

• Animal activity

• Temperature changes

How do plant roots contribute to weathering?

• By producing oxygen

• By absorbing water

• By growing into cracks and breaking rocks apart

• By providing shade

What is the result of repeated freeze-thaw cycles on rocks?

• Rocks split entirely

• Rocks become smoother

• Rocks change color

• Rocks become heavier

Which of the following IS a type of weathering?

• Chemical weathering

• Biological weathering

• Sedimentation

• Freeze-thaw weathering

What role do animals play in biological weathering?

• They polish rocks

• They dissolve rocks with acid

• They freeze water in cracks

• They burrow into rocks, weakening them

What is the primary factor that causes freeze-thaw weathering?
