Emergent coastline are the opposite of submergent coastlines, which have experienced a relative rise in sea levels.

Hudson Bay, in Canada's north, is an example of an emergent coastline. It is still emerging by
Coastline of the United Kingdom has a fractal dimension of 1.13, and that of South Africa is 1.02. As a result of this shape and the number of islands, the coastline of the UK is longer than that of similar sized countries. For example, the coastline of Italy is around 9,226 km in length, France 7,330 km and Spain 7,268 km. Greece, which has a large number of islands similar to the UK, has a coastline of around 15,147 km. This means the UK has a relatively high coast/area ratio. Nowhere in the UK is more than from the coast. It is estimated that around
