Answer:
- is nonrenewable,
- releases carbon dioxide when burned,
- forms from organic remains.
Step-by-step explanation:
- Coal is a natural resource that is a brown-black sedimentary rock and is formed by the interaction of gases like the carbon, nitrogen and the sulfur dioxide, inorganic, and the organic compounds and thus is a non-renewable resource.
- Like the fossil fuels and the anthropogenic sources like the deforestation and the there, formation dates back to the 360mn years ago. It has four major types like the peat, lignite anthracite and the bituminous and the graphite type.
- The anthracite and the bituminous are a high graded quality of coals as compared to the peat and the lignite. Due to this property of the coal, it's used to generate electricity and thus generate energy.
