Scientific definitions for bog


[ bôg ]

  1. An area of wet, spongy ground consisting mainly of decayed or decaying peat moss (sphagnum) and other vegetation. Bogs form as the dead vegetation sinks to the bottom of a lake or pond, where it decays slowly to form peat. Peat bogs are important to global ecology, since the undecayed peat moss stores large amounts of carbon that would otherwise be released back into the atmosphere. Global warming may accelerate decay in peat bogs and release more carbon dioxide, which in turn may cause further warming.
