- I have a question I hope someone out there can answer.
-
- The facts as I understand them: The beginning of life on Earth
- slowly evolved deep in the oceans, eventually creating oxygen
- that bubbled to the surface and then floated up to the
- stratosphere. About 30 miles from the surface, ultraviolet
- radiation acted upon it to create ozone, and ultimately there was
- enough created to form a buffer between the UV rays and the
- Earth.
-
- Question: As the UV rays were already bombarding the Earth, WHY
- did the reaction with the oxygen not create ozone at the ground
- level??
