Geo 101 – The Dynamic Earth Exam 4 Study Guide THIS IS NOT ALL INCLUSIVE – especially if you don’t fill it out fully.  What are the types of fossilization that we covered and how do they work o Frozen or Dried o Amber or Tar  Sticky sap on a tree, tar is when oil has seeped to the surface looking like a drinking hole o Preserved or replaced o Permineralization o Carbonization o Molds and Casts (Replica or original) o Trace Fossils o Extraordinary fossils (DNA)  What are evolution and natural selection o Evolution  Both fact and theory  Change in a population over a succession of generations, due to the transfer of inheritable characteristics o Natural Selection  Is theory that explains fact  Organisms are different  Same differences are advantages  More advantages = more offspring  Population of organisms are always changing to adapt to their environment  What are some the many pieces of evidence that help us understand how organisms evolve o Anatomy­ skeletons, teeth, anything left behind  Fossils  Modern o Vestigial organ  Organ that no longer functions in the same way that it did o Embryology  Way bone develops o Genetics  PNAS  Phylogenic relationships among the major cetartiodactly subgroups o Biogeography o Homology  The sameness  How anatomy looks the same in different creatures  What causes extinction o Climate change o Tectonic activity  Causes sea level to rise  Habitat changes o Asteroid or comet impact o New Predators  You must know the definitions of the relative dating techniques we covered in class and be able to use them like we did during the class activity. o Original Horizontality  How sediment is deposited  Fairly horizontal o Superposition  Applies to  Sedimentary only  Undeformed  Older on bottom  Can get tricky o Lateral Continuity  Sediments are deposited in continuous layers  Can be distributed later o Cross cutting relationships  Formations in relation to each other  Baked contact  Inclusions  What do unconformities tell us o Abrupt transitions in a stratigraphic column  Missing time  Non deposition  Erosion  How do geologists use fossils for dating o Principle of Fossil Succession  Fossils are found in limited strata  Found in a definable order (amphibians, mammals, etc.)  Don’t reappear o How we use fossil  Index fossils Trilobites  Well dated  Widespread  Short lived  How was the geologic column created o Represents entire Earths History o Graphic representation of the layers of rock that make up the earths crust o Divided into segments each of which represents a specific time interval  How does a radioactive isotope give us a numerical age o Decay and Half Life  Unstable atoms eject particles predictably  Become more stable atom (14C – 14 N)  Parent isotope  Daughter Isotope o Half Life  Time it takes for half of the population to decay  Cannot predict when single atom will decay  What characteristics does an object need in order to be dated with radio­isotopes o Carbon dating  What can be dated with radioactive methods  What other methods can you use to determine a numerical age o Igeneous rocks o Metamorphic  Sometimes, depends on temperature and mineral type  What did we date to determine the age of the earth o 4.5 Billion Years old  Know the major events in each eon or era that we covered in class: names of supercontinents, big geological events, types of life that first appeared.
