The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.

Explain how oxygen is connected to chemical weathering?
Both water and carbon dioxide contains an oxygen molecule. Water molecules combines with carbon dioxide when rain falls through the atmosphere. Water that seeps through the ground also picks up carbon dioxide from decaying organic matter.The carbon dioxide dissolved in water forms carbonic acid. This is the weak acid in carbonated soft drinks. Carbonic acid reacts with many common minerals.CO2 + H2O ↔ H2CO3 ↔ H+ + HCO3-
