Divided into 2 smaller categories:

5. Formation of the Earth Nebular HypothesisC D E B
Nebular Hypothesis
There was a giant cloud of hydrogen and helium gas
5 billion years ago, the cloud contracted (got smaller)
Formed a flat disk shape with the protosun (Pre-sun) in the center

6. Formation of the Earth Nebular HypothesisC D E B
Nebular Hypothesis
Inner planets begin to form from metallic and rocky clumps.
Larger outer planets began forming from fragments with a high percentage of ices

8. Formation of the Earth Earth’s Layers
Temperatures of the inner earth increased, causing melting.
This allowed the elements that were more dense to sink towards the center
Lighter rocky components floated outward, toward the surface.
Gaseous material escaped from Earth’s interior to produce the primitive atmosphere
