Landforms: Swamp, Marsh, Fen, or Bog

Wetlands come in different forms and have different characteristics, even though most people use the above words interchangeably in literature and general conversation, they each describe a different biome. Answer the questions about the characteristics to place them in the correct catagory.
Though some of these have fresh and saltwater varieties, I have restricted the quiz to freshwater varieties.
