Solution
Peat is an organic brown material which get accumulated when a plant material is decomposed partially. This usually occurs in wet areas where flooding do not provide the correct acidic and anaerobic conditions for full decomposition of plant.
Landscapes covered in peat also have specific kinds of plants, particularly Sphagnum moss, ericaceous shrubs, and sedges.
Peatland plants capture the CO2 which is naturally released from the peat. In Peatland the annual rate of biomass production is greater than the rate of decomposition. Soils that contain mostly peat are known as histosols. Peat is harvested as an important source of fuel in certain parts of the world.
As because organic matter get accumulated over thousands of years, peat deposits also provide records of past vegetation and climates stored in plant remains, particularly pollen. Hence, they allow humans to reconstruct past environments and changes in human land use.
