bog Scientific  
/ 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.

Explanation

You'd be pretty soggy by morning if you accidentally set your tent up in a bog. A bog is a swampy kind of ground made up mostly of decomposing plants and mosses. Nothing can be built on a bog because the ground is so spongy and damp, and no crops can be grown there. The dried soil from a bog can, however, be dried and burned for fuel. A figurative bog is anything that you tend to get stuck in, like a bog of health problems. Things can also "bog you down", or slow you down literally or figuratively, like when your homework bogs you down so you can't enjoy the weekend.
