    4.4 billion years ago

    earth started to cool and solidify.
    water began to form
  • 4 billion years ago
    4000 BCE

    4 billion years ago

    earth is covered in water vapor. 90 percent water. small volcanic islands. the oceans were green do to a surplus of iron. the atmosphere was thick with carbon dioxide, making the air thick and red.
  • 3.4 billion years ago
    3400 BCE

    3.4 billion years ago

    oceans dominated, granite appears from basil and saltwater, continents begin to form.
  • 2.5 billion years ago

    1.5 billion years ago

    blue planet
    oxygen is in the water which oxidized out the iron
    continents are moving
  • 1 billion years ago

    1 billion years ago

    rodinia is formed over the south pole blocking the currents
  • Cambrian (Paleozoic Era)

  • Triassic (251 MYA)
    251 BCE

    Triassic (251 MYA)

    volcanic eruptions happen at a global level, 95% of species have gone extinct, pangaea is formed, oxygen levels increase, and dinosaurs evolve.
  • Jurassic (201 MYA)
    201 BCE

    Jurassic (201 MYA)

    volcanic activity breaks up pangaea, high carbon dioxide levels warm up the planet, tropical forests become dominant, oxygen levels high.
