    Planetary Acceleration

    Earth started orbiting around the sun and gradually falling into the orbit between Venus and Mars.

    Core Formation

    Earth formed and its crust cooled to become solid, the core was formed. As the collision caused the earth to heat up, the heavier materials began to sink while the lighter materials rose. This formed the different layers of Earth's core
  • 4500 BCE

    Formation of Moon

    An asteroid the size of Mars smashed into Earth. The energy that impacted the smash has caused the rest of the asteroid to orbit around Earth, and that's Moon.
  • Period: 4500 BCE to 2700 BCE

    Planetary Cooling

    planetary cooling formed the planet into a molten planet. Clumps of asteroids, meteors, and comets helped formed the planet into a sphere.
  • 4400 BCE

    Zircon

    The oldest known thing to have formed on Earth, zircon, formed along with solid crust.
  • 4000 BCE

    Plate/Continent Structure

    it's called Lithosphere
  • Period: 3900 BCE to 3800 BCE

    Late/End of Heavy Bombardment

    The frequent collisions on Earth and Moon within the inner Solar System
  • 3800 BCE

    Ocean, Atmosphere, and Oxygen were found

  • Period: 3400 BCE to 2400 BCE

    Photosynthetic elements appeared on Earth
