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
.
