Land bridge

A land bridge, in biogeography, is an isthmus or wider land connection between otherwise separate areas, over which animals and plants are able to cross and colonise new lands. A land bridge can be created by marine regression, in which sea levels fall, exposing shallow, previously submerged sections of continental shelf; or when new land is created by plate tectonics; or occasionally when the sea floor rises due to post-glacial rebound after an ice age.
==Prominent examples==

* The Bering land bridge, which intermittently connected Asia with North America as sea levels rose and fell under the effect of ice ages
* Doggerland, a former landmass in the southern North Sea which connected the island of Great Britain to mainland Europe during the last ice age
* The Isthmus of Panama, whose appearance three million years ago allowed the Great American Interchange
* The Sinai Peninsula, linking Africa and Eurasia
* The Adam's Bridge (known as Rama Setu), connecting India and Sri Lanka
