Coastal Landscapes: Erosion, Transportation and Deposition Quiz

Which of the following is NOT one of the main processes of marine erosion?

• Hydraulic power
• Abrasion
• Attrition
• Sedimentation

What is the process of erosion where waves compress air in rock cracks, causing them to widen?

• Abrasion
• Attrition
• Hydraulic power
• Solution

Which erosion process is also known as corrasion?

• Hydraulic power
• Abrasion
• Attrition
• Solution

In the process of attrition, what happens to the eroded particles?

• They dissolve
• They become larger
• They become more angular
• They become more rounded

Which process is responsible for moving material along the coast?

• Tidal currents
• Longshore drift
• Wave refraction
• Coastal squeeze

In longshore drift, what determines the direction of material movement?

• Wind direction
• Tidal currents
• Prevailing wind
• Wave direction

What wind process moves material to the back of the beach by lifting it into the air?

• Drift

• Saltation

• Creep

• Suspension

When does deposition occur in coastal environments?

• When water speed increases
• When waves become stronger
• When water loses energy and slows down
• When tides are at their highest

Which statement is most true about coastal deposition?

• It only occurs during high tide
• It happens when erosion is greater than deposition
• It builds up coasts when deposition exceeds erosion
• It is unaffected by wave energy

What type of waves are more likely to cause deposition?

• Destructive waves
• Constructive waves
• Tsunami waves
• Rogue waves
