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. Land bridges 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.

Famous quotes containing the words land and/or bridge:

    Gone are the days when my heart was young and gay,
    Gone are my friends from the cotton fields away,
    Gone from the earth to a better land I know,
    I hear their gentle voices calling “Old Black Joe.”
    Stephen Collins Foster (1826–1864)

    London Bridge is broken down,
    Dance o’er my lady lee,
    London Bridge is broken down,
    With a gay lady.
    How shall we build it up again?
    Dance o’er my lady lee,
    —Unknown. London Bridge (l. 1–6)
