13329.	Question : Peat' is an important source of domesticfuel in several countries. How is 'peat' formed in nature ?
Answer» Solution :Peat an organicfuel consisting of spongy material formed by the partial decomposition of organic MATTER, primarily plant material in wetlands such as swamps ferns and mosses. The development of peat is favoured by WARM, moist climatic conditions The main PRODUCERS of peat Sphagum most occurs in bogs. The accumulation of Sphagnum plant in due course of time lead this plant to GET hardened and change into peat.
