Levels of sedimentary rock discovered nearer to the surface of Earth are youthful and fashioned additional lately. Levels of sedimentary rock identified further in Earth are more mature and formed much longer ago. In the same way, fossils located in these distinct levels of sedimentary rock can help scientists estimate the age from the fossil and a lot of things about how the organism lived. The entire process of employing rock strata to estimate the age of fossils, or levels in the sediment, known as relative relationship. Study Out Loud
