Coastal Erosion L5

What is a wave-cut platform?

• A sandy beach formed by wave deposition

• A flat area formed at the base of a cliff due to erosion

• A raised area of land formed by sediment deposition

• A deep underwater trench formed by tectonic activity

Reorder the following to explain the formation of a wave cut platform.

• Over time a wave cut notch is formed at base of the cliff

• Material is deposited at the base of the cliff creating a wave cut platform

• Sea attacks base of the cliff

• The cliff face becomes unstable and collapses.

• The cliff retreats.

Which process primarily contributes to the formation of wave-cut notches?

• Sediment deposition

• Volcanic activity

• Chemical weathering

• Coastal erosion

What is the main difference between soft and hard rock coastlines?

• Hard rock coastlines are always found in tropical regions

• Soft rock coastlines are more resistant to erosion

• Soft rock coastlines erode faster than hard rock coastlines

• Hard rock coastlines are made of sedimentary rock

Which of the following is a feature of coastal erosion?

• Wave cut platforms

• Sand dunes

• Coral reefs

• Mangrove forests

What is the primary factor that influences the rate of coastal erosion?

• The type of rock present

• The amount of sunlight

• The presence of marine life

• The temperature of the water

What is a headland in coastal geography?

• A narrow piece of land that projects into the sea

• A flat area formed by wave deposition

• A deep underwater trench

• A sandy beach formed by sediment accumulation

Which of the following is a result of longshore drift?

• Formation of sea arches

• Creation of spits and bars

• Development of coral reefs

• Growth of mangrove forests
