Weathering, Erosion, and Deposition Quiz II

What process is responsible for washing away soil and moving it downhill?

• Wind erosion

• Water erosion

• Chemical weathering

• Glacial movement

How do waves contribute to the formation of beaches?

• By carrying rocks to the shore

• By dropping sand from the ocean

• By dissolving minerals in rocks

• By freezing and expanding in cracks

What is a moraine formed by?

• Acidic rainwater dissolving limestone

• Wind carrying small sediments

• Glaciers dropping rocks they pushed in front of them

• Sediment from a river forming a delta

What causes rocks in rivers to become smooth?

• The wind eroding the rocks

• The rocks dissolving in acidic rainwater

• The rocks rubbing against each other as they move

• Tree roots growing and prying the rocks apart

How do tree and plant roots break apart rocks?

• By dissolving minerals in the rocks

• By carrying sediments to another location

• By digging into small cracks and growing

• By freezing and expanding in the cracks

What natural process is illustrated by wind carrying small pieces of sand that hit rocks and carve arches and other formations?

• Chemical weathering

• Water erosion

• Wind erosion

• Glacial movement

What is the role of acids in rainwater according to the image?

• They freeze and break rocks

• They carry sediments to new locations

• They dissolve minerals in rocks, wearing them down

• They drop sand from the ocean to form beaches

How is a delta formed?

• By wind picking up and carrying small sediments

• By sediment from a river dropping at the mouth

• By gravity pulling rocks downhill

• By water freezing and expanding in rock cracks

What geological feature is created by acidic rainwater dissolving limestone underground?

• Arches

• Deltas

• Moraines

• Caves

What causes the breakage of rocks through the process of freezing and expanding?

• Acidic rainwater

• Gravity

• Water getting into cracks

• Wind erosion
