View Notes - Chapter_25_Learning_Objectives from BIOL at LSU. • Explain how radiometric dating can be used to determine the absolute age of rock strata. Concept Key events in life's. Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand. Explain how index fossils can be used to determine the relative age of fossil- bearing rock strata. Explain how radiometric dating can be used to determine the absolute age of rock strata. Explain how magnetism can be used to date rock strata. Index fossils are a starting point for the relative age of the fossils and rock around.

Each fossil species reflects a unique period of time in Earth's history. Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type. There are many other methods that can be used to establish ages for parts of the earth and the solar system. Tetrapods became more common as organisms adapted to land.
