  7. 7. Varying Atmospheres Mars-- Cold, all water is frozen. Atmosphere 100 times thinner than Earth’s. Clouds of ice and frozen CO2 drift over the surface. ! Venus-- A stifling inferno! Surface temperatures greater than 8600 F. Atmosphere 100 times thicker than Earth’s, made up almost completely of CO2. ! Earth-- A developed Carbon Cycle keeps Earth habitable. Temperatures vary over the planet but remain liveable.

  15. 15. The Cambrian Explosion and the Diversification of Animals Maribeth Villanueva, Period 4
  16. 16. What is The Cambrian Explosion? “The rapid diversification of multicellular animal life that took place around the beginning of the Cambrian Period. It resulted in the appearance of almost all modern animal phyla.”
  17. 17. What about phyla? “The primary subdivision of a taxonomic kingdom, grouping together all classes of organisms that have the same body plan.”
  18. 18. How did this happen? Growing organisms that later evolved into more complex life forms created an “ecological relationship” that had a distinct role in much larger organisms and a rising oxygen level in the atmosphere. Also, there was a mass extinction at the end of the Proterozoic era, right before the Cambrian, so the environment flourished.
  19. 19. What happened during this? Life took 3 giant steps.
  20. 20. The Evolution of Early Mammals By: Geoff Ashton
  21. 21. With Old Endings Come New Beginnings ● Mammals were the size of rodents ! ● KT-Boundary Extinction ! ● Very few predators ! ● Held an internal temperature ! ● Mammal’s went all over Laurasia and Gondwanaland
  22. 22. Angiosperms ● Dominant form of land plants ! ● Seeds were enclosed inside the structure ! ● Fertilized ovaries grew ! ● Became the main type of plant life
  23. 23. Climate Fluctuations ● Extreme warming in the cenozoic era due to the breakup of Gondwanaland ! ● Ocean currents trapped by Antarctica ! ● Led to our most recent ice age
  24. 24. Apes in Africa ● Australopithecus ! ● The Genus Homo ! ● Homo erectus went from Africa to China and Eurasia ! ● Homo Sapiens settled in europe, 30,000 years later, North America
