Which is an advantage of safely using uranium as an energy source, rather 1 point than using coal? *
Uranium produces energy without polluting the atmosphere, while burning coal can
increase the CO2 in the atmosphere.
Uranium reduces the amount of thermal pollution, while burning coal can increase the
amount of thermal pollution.
Uranium is the most cost-efficient energy resource, while coal is the most expensive
energy resource.
Uranium can be easily mined from deep within Earth, while coal is a hard resource to
mine from deep within Earth.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
