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