When you breath, you exhale carbon dioxide. More CO2 enters the atmosphere from fossil fuels, deforestation, volcanoes, etc.
Although more carbon dioxide comes from natural decaying processes like rotting vegetation and dead creatures, that carbon was pulled out of the atmosphere by those same organisms earlier in the same annual cycle. We have charted the seasonal variation of atmospheric CO2, and without the human contribution from fossil fuel burning it would change very little from year to year. Most new atmospheric CO2 is liberated by the burning of coal and oil.
Volcanoes certainly produce some CO2, but unlike man these still very minor overall contributors.
Into the atmosphere as carbon dioxide.
Carbon dioxide goes back to the atmosphere through respiration, the decomposition of plants and animals, and combustion.
After carbon dioxide is released into the atmosphere, it can be absorbed by plants through photosynthesis, dissolved in the oceans, or remain in the atmosphere contributing to the greenhouse effect.
Carbon dioxide rises in the atmosphere.
No. Carbon dioxide is thoroughly mixed into the atmosphere and cannot separate from the air simply though gravity. Some carbon dioxide does go into water to become locked away in carbonate minerals, but the primary way of removing carbon dioxide from the atmosphere is through photosynthesis, a process by which plants and algae convert water and carbon dioxide into sugar and oxygen. Currently we are producing more carbon dioxide than the plants can absorb, resulting in an increase in the carbon dioxide in the atmosphere.
Carbon dioxide (CO2) is the molecule that carries most of the carbon in the atmosphere.
Yes, I think soil can emit carbon dioxide into the atmosphere.
The process of decay releases carbon dioxide into the atmosphere
carbon dioxide
Trees absorb carbon dioxide from the atmosphere during photosynthesis. When trees are cut down and not replaced, this carbon dioxide is no longer absorbed, leading to an increase in its levels in the atmosphere. Additionally, when trees are burnt or decompose, the stored carbon is released back into the atmosphere as carbon dioxide.
Carbon is stored in the atmosphere primarily as carbon dioxide (CO2) molecule.
Most of the carbon in the atmosphere is in the form of carbon dioxide, (CO2) gas.
