Chayil's Geology Timeline

  • Beginning of Earth
    4500 BCE

    Beginning of Earth

    Earth was originally Molten with high temperatures.
  • Cooling Down
    4400 BCE

    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.
  • Millions of Years of Rain
    4000 BCE

    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.
  • Creation of Continents
    3400 BCE

    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.
  • First organism
    2500 BCE

    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.
  • Continental Drift
    1500 BCE

    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.
  • Life in waters
    1000 BCE

    Life in waters

    Rodinia was a lifeless continent, life only existed in the waters,
  • Frozen Earth
    700 BCE

    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.
  • Rodinia's Doom
    650 BCE

    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.
  • Cambrian - Paleozoic Era
    541 BCE

    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.
  • Ordovician
    485 BCE

    Ordovician

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

    Silurian

    Shortest period of the Paleozoic era.
  • Devonian
    419 BCE

    Devonian

  • Carboniferous
    358 BCE

    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.
  • Permian
    289 BCE

    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.
  • Triassic - Mesozoic Era
    251 BCE

    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.
  • Jurassic
    201 BCE

    Jurassic

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

    Cretaceous

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

    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.
  • Quaternary
    2 BCE

    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.
