P1B Coasts Erosion Landforms

The main reason why headlands and bays occur on the same stretch of coastline.

• Erosion occurs only in bays.

• Erosion occurs only on headlands.

• The coast has alternate hard and soft areas.

• The waves are concentrated by refraction on the bays.

Choose the correct statement about erosional platforms.

• They are above the high tide level.

• They are always submerged

• They are formed by sub-aerial erosion

• They are the remains of old cliffs

Choose the correct statement/s about the collapse of sea cliffs

• Caused by both marine and sub-aerial erosion.

• Cliffs consisting of granite which are less resistant to erosion.

• The rate of collapse is slower for soft rocks.

• Burrowing animals has no effect on the collapse of the cliff

Choose the correct statement/s about marine terraces.

• They are the remnants of old erosional platforms.

• They are formed when the land is uplifted.

• They are formed when the ocean level dropped

• All of the previous statements are correct.

Identify the concave (hollow) area at the bottom of the cliff.

• cave

• arc

• notch

An erosion platform is slowly worn away by abrasion. What is the origin of the abrading rocks?

• They are from nearby cliffs

• Longshore drift carries them along.

• They are brought in by rivers
