Describe how coal is formed from dead vegetation .What is this process called
The formation of coal begins in areas of swampy wetlands where groundwater is near or slightly above the topsoil. Because of this, the flora present produces organic matter quickly - faster in fact than it can be decomposed. In these areas, layers of organic matter are accumulated and then buried.
Because coal takes millions of years to develop and there is a limited amount of it, it is a nonrenewable resource. The conditions that would eventually create coal began to develop about 300 million years ago, during the Carboniferous period.
There are four stages in coal formation: peat, lignite, bituminous, and anthracite. The stage depends upon the conditions to which the plant remains are subjected after they were buried – the greater the pressure and heat, the higher the rank of coal.
