It's the most abundant fossil fuel we have. The four types of coal include peat, lignite, bituminous, and anthracite, with anthracite being most desirable due to its high heat content. Coal was formed millions of years ago during the Carboniferous Period from ancient plants found in swamps and bogs.
2)Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.
3)The iron is protected even if the coating is scratched. The more reactive metal reacts with the air and water instead of the iron, so the irondoes not rust. The atoms of the more reactive metal form ions rather than those of the iron (preventing the formation of the Fe3+ ions present inrust).
