Uranium (c) is Not classified as a fossil fuel
The reason why is because ..
Fossil fuels such as Coal , oil , and natural gas are considered "fossil fuels" because they were formed by the buried remains of "animals and plant"s that have lived millions of years ago.
However , Uranium is mined and then converted into a fuel but used for "nuclear power plants".
Therefore , that does not make Uranium a "Fossil Fuel" as it is not made or used from fossils of animals and plants , making or using it as a "fossil fuel" but as a fuel for the nuclear power for plants
