minerals dated by radioactive isotopes in a sedimentary rock are usually: group of answer choices older than the sedimentary rock the same age as the sedimentary rock unreliable younger than the sedimentary rock

Radiometric dating is not accurate for sedimentary rocks because they have multiple origins of the source material. This means that the radioactive materials in them came to the surface of the earth at different points and as a result, they have a mixture of ages.Radiometry is a set of ways for measuring electromagnetic radiation, including visible light. Radiometric ways in optics characterize the distribution of the radiation's power in space, as opposed to photometric ways, which characterize the light's commerce with the mortal eye. Radiometric amounts are amounts related to electromagnetic radiation. Radiant Energy is energy carried from any electromagnetic field. The difference between radiometry and photometry is that radiometry includes the entire optic radiation diapason( and frequently involves spectrally resolved measures), while photometry deals with the visible diapason ladened by the response of the eye.
