What are the 4 stages of coal formation?

There are four stages in coal formation: peat, lignite, bituminous, and anthracite.

What are disadvantages of coal?

The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
