How is uranium 235 formed
WebSolved by verified expert. 1) Determining the ages of igneous rocks by isotopic methods can help to date fossils because many fossils are found in sedimentary rocks that were formed from the erosion of nearby igneous rocks. By determining the age of these igneous rocks, it provides an approximate timeline for when the sediments were formed. http://large.stanford.edu/courses/2024/ph241/jones-j1/
