    Coal - Wikipedia

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

    Uranium | Geoscience Australia

    Uranium (U) is a radioactive element that averages one to four parts per million in the Earth's crust. Natural uranium contains about 0.7% of the U 235 isotope (the fissile isotope) and 99.2%of the U 238 isotope. Concentrations of uranium minerals such as uraninite, carnotite and brannerite can form commercial deposits.

    Differences Between Coal Energy and Nuclear .

    Nuclear energy uses enriched radioactive elements like uranium to produce heat in a process called nuclear fission. This process needs to be carefully monitored in order to prevent the excessive production of heat and consequent plant meltdown. In contrast, coal energy uses coal, a fossil fuel that is burned to produce heat.
