'Peat' is an important source of domestic fuel in several countries. How is 'peat' formed in nature?
Ans. Partially decayed and degenerated vegetation and organic matter accumulate to form peat. When plant substances present in generally wet areas do not decay completely due to acidic and anaerobic environment conditions, it leads to the formation of peat. This wetland vegetation is the main component of peat. The main producer of peat is Sphagnum. However, several other plants may also be included in the formation of peat. Most of the modern peat was formed in high latitudes when the glaciers retreated in the ice age.
This phenomenon took place around 12,000 years back. Peat accumulates at a terribly slow rate of around 1 millimetre a year.Peat proves to be a major source of domestic fuel in several countries like Europe and America. It is also valuable in improving the fertility of the soil.
