Constructive waves have strong backwash and weak swash
True
False
Which of the following geographical term means the wind which predominantly blows over a period of time?
Wind speed
Monsoon
Prevailing wind
Fetch
Which of the following is NOT a type of coastal erosional processes?
Solution
Saltation
Hydraulic Action
Attrition
The strength of the wave is dependent on ... (click all suitable options.)
wave direction
wind speed
fetch
wind duration
The process when rock particles knock against the base of the cliff causing parts of the cliff to breakdown.
Attrition
Solution
Hydraulic Action
Abrasion
Air is trapped the cracks of cliffs by the force incoming waves. The pressure buildup causes the joints to weaken and rocks to shatter.
Abrasion
Attrition
Hydraulic Action
Solution
Define the term "erosion"
The destruction of a coastline
The build up of minerals and sand
The wearing away and breakdown of rocks and material
Forming landforms
Constructive waves create beaches
False
True

What is a coast
Land next to the ocean
The edge of a desert

What are the parts of a wave?
Backshore, offshore, dunes, foreshore
Wavelength, crest, trough, wave height

I don’t know
Deposition occurs when
Wave energy is high
Wave energy is low
All of the above
None of the above
The acids in seawater slowly dissolve the chalk and limestone cliffs. The material produced is carried away by this process.
Hydraulic action
Corrasion
Attrition
Solution
It is how far the wave has traveled.
Erosion
Deposition
