Blackmoor Vituperative

I learned an interesting thing at the Virginia Aquarium the other day. A swamp is not a bog, nor are either of these marshes. A swamp has trees, water, and mud. A bog has trees, water, and decaying vegetation which is decaying more slowly than it builds up. A marsh has grass, water, and mud, and is either a salt marsh or a freshwater marsh, depending on how close it is to the ocean and how much brackish water the tide brings in. The Virginia Aquarium is located right on top of a salt marsh, and the exhibits on the marsh ecosystem are really interesting.
