Coastal Landforms

Which answer best explain why are there no longer 12 Apostles?

• Because of tectonic plate movements.

• Because of the highly erodible limestone and wave impact.

• Because of weathering.

• Because of earthquakes.

What is coastal erosion MOSTLY caused by?

• Roads being built along coastal areas.

• Surfers using the ocean to surf.

• Waves moving sand and other material to and from beaches.

• Chemical weathering slowly moving sand.

What is being shown in the image above?

Hint: relates to the erosion process.

• Backwash returning sand to the coast line.

• Convergent waves.

• Backwash carrying sand away from the coast.

What other factors influence coastal erosion? Choose TWO answers.

• Earthquakes and volcanoes.

• Human activity on the coastline.

• Stormy weather with destructive waves.

• Butterflies floating in the air.

Why are destructive waves so damaging to sandy coastlines? Choose all that apply.

• They can remove sand from a beach.

• They can create thunderstorms.

• They can remove management features designed to protect coasts.

• They can destroy vegetation holding sand together.

What are constructive waves?

• Waves that destroy the coastline.

• Waves that carry less energy and deposit sand along the coast.

• Waves that carry lots of energy and deposit sand away from beaches.

• Waves that carry less energy and cause flooding.

What is longshore drift?

• When the wind directs the angle of waves towards the coast resulting in materials being moved along a coastline.

• When the wind directs waves away from the coast resulting in harmful erosion.
