The strength of the wind is dependent on ... (click all suitable options.)
wave direction
fetch
wind speed
wind duration
Fetch refers to

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 at the the cracks of cliffs by the incoming waves. The pressure buildup causes the joints to weaken and rocks to shatter.
Hydraulic action
Solution
Attrition
Abrasion
