Emergent coastline
An emergent coastline is a stretch along the coast that has been exposed by the sea by a relative fall in sea levels by either isostasy or eustasy.
Emergent coastline are the opposite of submergent coastlines, which have experienced a relative rise in sea levels.
The emergent coastline may have several specific landforms:
- Raised beach or machair
- Wave cut platform
- Sea cave such as King's Cave, Isle of Arran
Hudson Bay, in Canada's north, is an example of an emergent coastline. It is still emerging by as much as 1 cm per year. Another example of emergent coastline is the Eastern [Coastal Plains] of the Indian subcontinent.
