Early Earth & Space Science

Planetary Accreation

4 BCE

This is where the Earth originated 4.6 Billion years ago. It formed because of gravity where it brought lots of pieces of rock floating around creating the basis of the Earth

Formation of the Moon

4 BCE

The Giant Impact Thesis: This thesis explains that the moon formed due to an object crashing into early earth which sent leftover cloud and dust into space where it formed around theias core and was the moon

Planetary Cooling

4 BCE

During this period around 4.5-3.8 Billion years ago, we can see that the eath was starting to form with some of it starting to create what we know as the Earth. We also know that when looking at things like this we know that around this date where the first rocks were formed which we know by using radiocarbon dating. This is also when the earths core started to form

Core Formation

3 BCE

Evidence has shown that the earth's core may have formed due to lots of different layers of rock breaking apart forming the different parts of the earths core It was found in 2003 at Oyakama University.

End of Heavy Bombardment

3 BCE

The end of the heavy bombardment was around 3.8-3.6 billion years ago and it was when asteroids and smaller planetary substances came and hit the planets, examples of this are with planets such as the moon Saturn or venus.
