Wave Erosion Quiz

What are the three factors that the power of waves to erode depends on?

• The strength of the wind, the duration of the wind, and the fetch-length

• The temperature of the water, the depth of the sea, and the strength of the wind

• The salinity of the water, the duration of the wind, and the wave height

• The wave height, the temperature of the water, and the fetch-length

What is the term used to describe the movement of water up the beach?

• Swash

• Backwash

• Erosion

• Deposition

Which type of wave is described as flat and low, carrying material up the shore and depositing it there?

• Destructive waves

• Constructive waves

• Corrosive waves

• Hydraulic waves

What is the process called when waves compress the air in the cracks of cliffs, causing the cracks to widen and the rocks to break up?

• Corrosion

• Attrition

• Solution

• Hydraulic action

How are materials sorted when deposited by waves?

• According to color

• According to size

• According to weight

• Randomly

What are headlands and bays formed as a result of?

• The uniform erosion of rocks

• Alternate bands of harder and softer rocks

• The deposition of sand and pebbles

• The retreat of cliffs due to erosion

Why are headlands more vulnerable to erosion?

• They are composed of softer rocks

• They stick out into the sea and are subject to wave action

• They are protected by natural barriers

• They are composed of sand and pebbles

What happens to the sand and pebbles eroded from the headlands?

• They are deposited as beaches in bays

• They form alternate bands of rocks

• They cause the headlands to retreat

• They are dissolved by acids in the water

What processes contribute to the erosion of cliffs?

• Hydraulic action and solution

• Corrosion and deposition

• Attrition and wave-cut platforms

• Headlands and bays formation

What is the result of the base of the cliff being eroded away?

• Formation of a wave-cut platform

• Development of headlands

• Creation of bays

• Deposition of sand and pebbles
