Mock Geology Presentation

  1. 1. A [Legendary] Tour of the History of Earth
  2. 2. Centaurus all dressed up to show the Planetary Accretion occurring in the beginning stages of our solar system forming.Cent equips some safety glasses as thesun’s UV rays were quite strong back inthe Precambrian (mainly due to lack of a mature atmosphere). Here she is showing an example of the massive volcanic gassing occurring.
  3. 3. Red Beds were a quite prominent feature in the Precambrian as well. Here Cent shows an excellent example! Cent has her friendMagnitude do a fly over of the first Ice Age in the Precambrian.
  4. 4. Cent has discovered a nice example of Ediacaran Fauna that were prominent in water environments in the Precambrian.What’s that? Yes, you guessed it, Acritarchs! (seen under the microscope, of course!)
  5. 5. Lucky Cent discovers some exposed parts of the North American Craton!Here, Magnitude scouts out some awesome shots of the Earth’s lithosphere forming!
  6. 6. Could it be? YES, Cent has found the Burgess Shale! The Burgess Shale is the is the most well preserved snapshot of fauna from the Cambrian period. Another common feature in the Paleozoic were the Epeiric Seas.They were warm shallow seas that covered much of the planet.
  7. 7. Near the end of the Paleozoic the Earth went through another period of global cooling. Cent has her friend Magnitude check it out (Cent doesn’t like being cold).
  8. 8. The Paleozoic saw its first land plants. Most of the first plans were ferns, and they grew quite large.Here Cent finds a pinecone! These early gymnosperms first appeared in the Paleozoic.
  9. 9. Cent has her dagger ready in case this Dimetrodon attacks! Dimetrodon first appeared in the Paleozoic.Here Cent is pointing out someamniotic eggs, which also were new in this time period.
  10. 10. It’s time to refer to the map, Cent examines what Pangaea looked like when it formed in the Paleozoic. There were many subductionzones like this one here. Here an oceanic plate is colliding with a continental plate.
  11. 11. The Mesozoic went through three periods of cooling. Cooling occurred during the end of the Triassic, Jurassic, and Cretaceous. Cent has her bf Magnuuz getthese exclusive shots of the bolide impact crater that led to themass extinction at the end of the Mesozoic.
  12. 12. Pollinating Insects first appeared in the Mesozoic.Magnitude sneaks up on a groupof Dinosaurs who peaked in the Mesozoic.
  13. 13. Magnuuz gets a lucky shot of a Plesiosaur!
  14. 14. The Rocky Mountains and The Sierra Nevadas form from the Laramide Orogeny and Nevadan Orogeny. During the Mesozoic thesupercontinent Pangaea starting the rifting process, slowly spreading apart. (Cent uses her map to show the process.)
  15. 15. Here you can see a basin and range event, they are distinguishable because of the rippled/stretched appearance. The Cenozoic also saw another ice age.(why does the Blood Elf have to do all the dirty work?)
  16. 16. Angiosperms dominated the Cenozoic and were 90% of all the floura.The Great Irish Elk was another species that lived during the Cenozoic.
  17. 17. Other life forms appearing in the Cenozoic:Dire Wolves Whales Goblins? Humans Primates
  18. 18. Vigorous volcanism occurred with large intrusions of magma during the Cenozoic. Also taking place were many events causing faults. Onefamous fault that formed in theCenozoic was the San Andreas, which is a transform fault.
  19. 19. Cent and her friends hope you enjoyed your tour!
