ERS103H5 Study Guide - Midterm Guide: Seismic Wave, Ediacaran Biota, Absolute Dating
Document Summary
Five interacive spheres control every aspect of life on this planet through posiive and negaive feedbacks. It is born, it grows, it moves, it shrinks, and it dies. Relaive and absolute daing combine to give us a precise means of telling geological ime. Weathering, erosion, transport, deposiion and lithiicaion of sediments leads to the formaion of sedimentary rocks. Understanding these processes allows you to interpret ancient environments. Plant remains and animal shells + skeletons form biogenic rocks. Understanding the biology of these organisms allows you to interpret ancient environments. The evoluion of life changed the nature of the earth. The evoluion of the atmosphere directly linked to the interacions between earth and. Geological evidence can be used to explore deep ime: fossils, isotopic signatures, distribuion and abundance of speciic minerals. Test questions: how do we study the inside of the earth, seismic studies allow for an indirect way of studying the interior of the earth;
