Question
‘Peat’ is an important source of domestic fuel in several countries. How is ‘peat’ formed in nature?
Solution
Peat is formed by the action of bacteria on partially degraded and decayed vegetation or any other organic matter.
Formation of Peat: Peat is formed when plant or vegetation material is inhibited from decomposing fully due to acidic and anaerobic conditions. This usually happens in wet areas due to the presence of moisture. Peat is majorly composed of wetland vegetation and its main producer is Sphagnum. The modern peats are formed at high altitudes after the retreat of the glaciers at the end of the last Ice Age. The accumulation of peat is very slow, about one millimetre per year.
Peat is an important source of domestic fuel in many countries and is also used in agriculture to add to the soil fertility.
