Coastal Processes Quiz

Can you beat our quiz?

Which of the following is not an example of a coastal process?

Deposition

Transportation

Plucking

Erosion

Correct! Wrong!

Plucking is a process of glacial erosion.

Which of the following are examples of coastal erosion?

Corrasion, abrasion, wave action, attrition and corrosion/solution.

Corrasion, abrasion, hydraulic action, attrition and traction.

Corrasion, abrasion, hydraulic action, attrition and suspension.

Corrasion, abrasion, hydraulic action, attrition and corrosion/solution.

Correct! Wrong!

Which type of coastal erosion involves destructive waves picking up beach material (e.g. pebbles) and hurling them at the base of a cliff?

attrition

corrasion

abrasion

hydraulic action

corrosion/solution

Correct! Wrong!

Commonly known as the sandpaper effect, which type of coastal erosion involves breaking waves, concentrated between the high and low watermarks, which contain sand and larger fragments wearing away the base of a cliff or headland?

hydraulic action

corrosion/solution

corrasion

abrasion

attrition

Correct! Wrong!

A type of coastal erosion that involves waves hitting the base of a cliff causing air to be compressed in cracks, joints and folds in bedding planes resulting in repeated changes in air pressure. As air rushes out of the cliff when the wave retreats it leads to an explosive effect as pressure is released. This process is supported further by the weakening effect of weathering. The material breaks off cliffs, sometimes in huge chunks.

abrasion

corrasion

attrition

hydraulic action

corrosion/solution

Correct! Wrong!

Which type of coastal erosion occurs when waves cause rocks and pebbles to bump into each other and break up?

attrition

hydraulic action

corrosion/solution

abrasion

corrasion

Correct! Wrong!

Which type of coastal erosion occurs when certain types of cliff erode as a result of weak acids in the sea?

abrasion

attrition

hydraulic action

corrosion/solution

corrasion

Correct! Wrong!

Which of the following is not a factor that affects rates of coastal erosion?

Geology

Strong winds blowing for a long time creating destructive waves.

The greenhouse effect.

Coastline with no beach to buffer the waves.

Wave fetch

Correct! Wrong!

The greenhouse effect is a natural process that traps the sun's warmth in the Earth's lower atmosphere.

Internet Geography

Waves enter an area of shallow water.

A river or estuary flows into the sea reducing wave energy.

There is a poor supply of material.

There is little wind.

Waves enter a sheltered area, eg a cove or bay.

There is a good supply of material and the amount of material being transported is greater than the wave energy can transport.

Correct! Wrong!

Coastal Processes Quiz

Boom! Well done!

Awesome, well done! You know your coastal processes.

Not bad...

As Thor says, not bad at all. But, let's be honest, it's not brilliant. Give the quiz another go and don't forget to read up on this area by heading over to our coasts resources using the topics link at the top of the page.
