Geography Mini Test: Coastal Processes

What is coastal erosion?

• The process of building up land along the coast

• The wearing away of rocks and land along the coast

Which of the following is a type of erosion?

• Hydraulic action

• Sand deposition

What happens in hydraulic action?

• Rocks hit each other and break apart

• Water and air get into cracks in rocks, breaking them apart

What is abrasion?

• Sand and pebbles scraping against rocks, wearing them down

• Rocks dissolving in seawater

What is attrition?

• Rocks breaking down as they hit each other

• Water dissolving the rocks

What is the solution process in coastal erosion?

• Waves deposit sand onto the beach

• Rocks dissolve in seawater

Which type of wave builds up beaches?

• Constructive waves

• Destructive waves

What is longshore drift?

• Movement of sand and materials along the coast by waves

• A type of strong wave that hits the beach directly

Which direction do materials move during longshore drift?

• Straight up the beach

• Along the coast, at an angle

What is the process of coastal transportation?

• When materials are worn down along the coast

• When materials like sand and pebbles are moved along the coast
