An emergent coast can form from isostasy.

Question

Quizplus · Accepted Answer

Isostasy refers to the balance between the land surface and the underlying mantle. If the weight on the land surface changes, due to things like erosion or deposition of sediment, the underlying mantle will adjust to maintain equilibrium. This can result in either uplift or subsidence of the land. If the land is uplifted, it can form an emergent coast. This can happen over a long period of time due to gradual changes, or more suddenly due to events like earthquakes or volcanic activity.
