Year 9 Geography Term 3b - The Coastal Zone

Name the three main coastal processes.

• Erosion, transportation, and deposition.

• Condensation, evaporation, and precipitation.

• Photosynthesis, respiration, and transpiration.

• Melting, freezing, and sublimation.

Describe the processes of erosion.

• Erosion involves attrition, solution, abrasion, and hydraulic action.

• Erosion is the process of rock formation through cooling magma.

• Erosion is the process of plant growth in soil.

• Erosion involves only the movement of tectonic plates.

Describe the processes of transportation.

• Transportation involves solution, suspension, saltation, and traction.

• Transportation involves only evaporation and condensation.

• Transportation involves photosynthesis and respiration.

• Transportation involves melting and freezing.

What is required for deposition to occur?

• Deposition occurs when energy is lost as water gets shallower or wind dies down, causing the heaviest material to be dropped first.

• Deposition occurs when temperature increases rapidly, causing all materials to rise.

• Deposition occurs when water flows faster, carrying heavier materials further.

• Deposition occurs when wind speed increases, lifting heavier materials higher.

Which process involves rocks in the load bashing together to become smoother or smaller?

• Attrition.

• Abrasion.

• Solution.

• Hydraulic action.

Which process involves a chemical reaction that dissolves rocks in cliffs?

• Solution.

• Abrasion.

• Attrition.

• Freeze-thaw.

Which process involves rocks hitting or rubbing against the base of a cliff and breaking pieces apart?

• Abrasion.

• Condensation.

• Evaporation.

• Oxidation.

Which process involves water entering cracks in the cliff, compressing trapped air, and putting pressure on the crack?

• Hydraulic Action.

• Abrasion.

• Solution.

• Attrition.

What is suspension in the context of coastal transportation?

• Sediment is carried along in the flow of the water.

• Sediment is dissolved completely in the water.

• Sediment is deposited on the beach immediately.

• Sediment is only moved by wind action.

What is saltation in the context of coastal transportation?

• Pebbles that bounce along the seabed.

• Sand that is dissolved in seawater.

• Large rocks that remain stationary on the seabed.

• Waves eroding the coastline.
