What role do humans play in erosion?

• No role

• They cause it

• They study it

• They prevent it

What happens during deposition?

• Rocks break down

• Water evaporates

• Sediment is moved

• Sediment settles

• False

• True

What is the main difference between weathering and erosion?

• Weathering and erosion both break rocks

• Weathering breaks rocks, erosion moves them

• Weathering moves rocks, erosion breaks rocks
