See also: Cliff (homonymy)

A cliff is an escarpment Roche ux created by the erosion along a coast. One can distinguish low cliffs (height lower than 2 Mètre S), average cliffs (between 2 and 10 meters) and high cliffs (more than 10 meters). The most cliffs of the world, the Kahiwa Falls, are located at Hawaii, on the island of Molokai, and make approximately 610 meters in height. With Umilehi Not, they reach 1.005 meters above the Pacific Ocean. The cliffs are formed:

either by the action of an erosion Horizontal E on a elevated Bank,
or by an action Vertical E of digging on a Substrate rock,
or still by a differential erosion on two types of Rock S, one being there more sensitive to than the other.

With the foot of cliffs are generally the remainders of their Effondrement S progressive, in the form of Amas of rocks. The importance of these clusters often depends on the sensitivity of the rock to erosion.

When a cliff is not any more in contact with water, one speaks about dead cliff . In the contrary case, one speaks about sharp cliff.
