cliff
A steep coastal declivity which may or may not be precipitous, the slope angle being dependent partly on the jointing, bedding and hardness of the materials from which the cliff has been formed, and partly on the erosional processes at work. Where wave attack is dominant the cliff-foot will be rapidly eroded and cliff retreat will take place, especially in unconsolidated materials such as clays, sands, etc., frequently leaving behind an abrasion platform at the foot of the cliff.
