Describe what the early atmosphere was like and what cause a large amount of oxygen (O2) to build up in the atmosphere?
Scientist have determined that the early Earth had no free oxygen anywhere. Briefly explain what evidence in
the rock layers that scientists found to prove when the early conditions on earth had free oxygen in the
atmosphere.
Was there molecular oxygen in the earth's primitive atmosphere? How has that molecule become abundant?
