  • 4,500 BCE

    Beginning of Earth

    Beginning of Earth
    Earth was originally Molten with high temperatures.
  • 4,400 BCE

    Cooling Down

    Cooling Down
    Earth is cooling down in temperatures, rocks and water was forming on the planet, as the planet cooled, it produced carbon dioxide. More water was coming from meteorites.
  • 4,000 BCE

    Millions of Years of Rain

    Millions of Years of Rain
    Large amounts of rain came down for millions of years, over 90% of its syrface was ocean. Green iron seas and red carbon seas.
  • 3,400 BCE

    Creation of Continents

    Creation of Continents
    Huge green oceans, under sea volcanic rock created the Continents. South Africa granite was everywhere produced by lava and water. Granite was light and tough.
  • 2,500 BCE

    First organism

    First organism
    After the continents had arrived, it helped make oxygen which helped life. The Stromatolite was the first organism to be seen. They needed sunlight, they were 2ft high and 1 foot across. It was made up of a thin layer of micro organisms that would build up layer by layer, they lived by photosynthesis, which helped create more oxygen.
  • 1,500 BCE

    Continental Drift

    Continental Drift
    The Earth now had blue oceans and a blue sky, the iron in the water had scattered into rocks. The continental drift happened at this time, this was proven by maps of the see floor.
  • 1,000 BCE

    Life in waters

    Life in waters
    Rodinia was a lifeless continent, life only existed in the waters,
  • -700 BCE

    Frozen Earth

    Frozen Earth
    Rodinia covered the South Pole, the warm water was blocked by it. The Earth ended up freezing over and it ended up losing about 95% of the Earth's species. Algae and bacteria dominated the world.
  • -650 BCE

    Rodinia's Doom

    Rodinia's Doom
    Beneath the ice, volcanic eruptions started splitting Rodinia and the heat from the volcanoes helped warm up and melt the snowballed Earth.
  • -541 BCE

    Cambrian - Paleozoic Era

    Cambrian - Paleozoic Era
    Rodinia is broken up and the ice is melted. The Cambrian explosion happens. Fossils found from this time had animals and creatures that would feed on plants and each other, soon there would be more different creatures then.
  • -485 BCE

    Ordovician

    Ordovician
    The new layer on the Earth's atmosphere, could let new life live on land.
  • -443 BCE

    Silurian

    Silurian
    Shortest period of the Paleozoic era.
  • -419 BCE

    Devonian

    Devonian
  • -358 BCE

    Carboniferous

    Carboniferous
    Became a world of swamps. The Carboniferous would dominate the world for the next 60 years of swamps. The tree decay can turn into coal on land, oil and gas are large fossil fuels from this time. Life comes from Carbon, oil is dead marine life from millions of years ago.
  • -289 BCE

    Permian

    Permian
    Life on land, reptiles, and insects. The crust became a volcanic fest, 1 million years of eruptions, poisonous gas was in the air and 95% of the species went extinct.
  • -251 BCE

    Triassic - Mesozoic Era

    Triassic - Mesozoic Era
    Dinosaurs were found to be in this era, and learned to be warm-blooded and were year round animals, unlike usual reptiles.
  • -201 BCE

    Jurassic

    Jurassic
    The dinosaurs still lived and populated this time period.
  • -145 BCE

    Cretaceous

    Cretaceous
    Still carried dinosaurs and the 7 continents were born due to volcanic eruption.
  • -50 BCE

    First Mammals

    First Mammals
    The first mammals, the himalayas and swiss alps are forming due to two continents hitting each other. The Matterhorn is the child of Africa and Europe. The top of the mountain is African. Eurasian helps stop them from overlapping.
  • -2 BCE

    Quaternary

    Quaternary
    Modern humans taking first steps on Earth. Earth was going to start the Ice Ages. Ice Ages lasting 10s of thousands of years, at -20 degrees.
