Peat
Peat is an accumulation of partially decayed vegetable matter. Peat forms in wetlands called peatlands, examples of which are bogs, moors, muskegs, mires, and fens. Peat deposits are the first stage in formation of coal deposits.
Peat is soft and easily compressed. Under pressure, water in the peat is forced out. Upon drying, peat can be used as a fuel, and is traditionally used for cooking and domestic heating in many countries including Ireland and Scotland, where stacks of drying peat dug from the bogs can still be seen in some rural areas. Peat is also dug into soil to increase the latter's capacity to retain moisture and add nutrients.
Dry peat beds can be a fire hazard. Peat deposits on the landscape pose a difficulty to builders of roads.
