What are bogs ?

A quagmire covered with grass or other plants, wet, spongy ground, a small marsh, plant community on wet, very acid peat is called bog

A bog is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, quagmire, and muskeg; alkaline mires are called fens.
