Radiometric dating does not usually work with sedimentary rocks because they **form from many older rock particles**. Sedimentary rocks are composed of particles from older rocks, and therefore, the age of the sedimentary rock does not reflect the age of the individual particles. Instead, radiometric dating is more effective with igneous and metamorphic rocks, which typically crystallize from molten material and can provide a more accurate age.
