Question 1 of 5
Erosion is the wearing away of the land by the sea.
Question 2 of 5
Match the 5 types of coastal erosion to the descriptions below.
is when waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff.
occurs as breaking waves which contain sand and larger fragments erode the shoreline or headland. It is commonly known as the sand paper effect.
is when waves hit the base of a cliff air is compressed into cracks. When the wave retreats the air rushes out of the gap. Often this causes cliff material to break away.
is when waves cause rocks and pebbles to bump into each other and break up.
is when certain types of cliff erode as a result of weak acids in the sea.
That’s not right I’m afraid. Give it another go.
Question 3 of 5
There are four main types of coastal transportation. Fill in the gaps below to identify them.
(Traction) is when large material is rolled along the sea floor.
(Saltation) is when beach material is bounced along the sea floor.
(Suspension) involves beach material being suspended and carried by the waves.
(Solution) is when dissolved material is carried by the water.
Correct 4 / 4Points
Incorrect / 4 Points
Sorry, that’s not right. The correct answer is:
Traction – large material is rolled along the sea floor.
Saltation – beach material is bounced along the sea floor.
Suspension – beach material is suspended and carried by the waves.
Solution – material is disolved and carried by the water.
Question 4 of 5
Deposition is when material that is being transported is dropped by constructive waves. It happens because waves have less energy.
Sorry, it’s true. Deposition is when material that is being transported is dropped by constructive waves. It happens because waves have less energy.
