Erosion Processes Quiz

What is the primary force behind hydraulic action in erosion?

• Sediment collision

• Chemical reactions

• Wind pressure

• Water force and air bubbles

How does abrasion contribute to erosion?

• By trapping air bubbles in water

• By rubbing and wearing away surfaces with sediment

• By increasing wave height

• By dissolving rocks in acidic water

What is the result of repeated grain collisions in a riverbed?

• Formation of larger rocks

• Creation of air bubbles

• Erosion of the riverbed

• Increase in water acidity

What happens during the process of attrition?

• Rocks dissolve in water

• Sediment grains collide and break

• Air bubbles erode rocks

• Waves crash against cliffs

Which type of rock is most affected by the solution process?

• Granite

• Basalt

• Sandstone

• Limestone
