Peat is plant material which is partially decomposed and has accumulated in waterlogged conditions.
Peatlands include moors, bogs and fens, as well as some farmed land.
Peat bogs are particular types of wetlands waterlogged by direct rainfall. Peat bogs grow slowly, accumulating around 0.5 to 1 mm of peat each year, and the water prevents the plants from decomposing. As a result, many areas of UK peat bog have been accumulating gradually for as much as 10,000 years, and can be up to 10m deep. Due to its slow accumulation, peat is often classified as a fossil fuel.
