Earth's atmosphere contains only small amounts of carbon dioxide because: chemical reactions with other gases destroyed the carbon dioxide and replaced it with the nitrogen that is in the atmosphere now. the earth's volcanoes did not outgas as much carbon dioxide as those on venus and mars. carbon dioxide dissolves in water, and most of it is now contained in the oceans and carbonate rocks. most of the carbon dioxide was lost during the age of bombardment. earth doesn't have as strong a greenhouse effect as is present on venus.

Answer

Earth's atmosphere contains only a small amount of water because the carbon dioxide dissolves in water and most of them are now contained in the oceans and carbonate rocks.

Carbon dioxide is absorbed in the ocean when air meets water. Winds cause waves and turbulence which gives the opportunity to absorption of Carbon dioxide in water.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
