Like Venus and Mars, most of our CO2 was probably there from the beginning, and has been pulled out and sequestered in limestone, chalk, coal and oil deposits over hundreds of millions of years.
For the past few million years, CO2 cycles from a low in the summer (when it is absorbed by growing plants, grass and leaves) to a high in the winter, as those organisms die and release their stored up carbon. This cycle continues, though it has gradually increased due to human fossil fuel consumption.
MOST of the additional CO2 in our atmosphere over the past century has come from the the burning of coal and oil.

Do cars omit carbon dioxide?
No, they release carbon and others from the exhaust but later the carbon goes through synthesis in which it forms carbon dioxide in the atmosphere.
What are the two ways in which carbon dioxide is added to the?
Respiration by animals is one of the ways through which carbon dioxide is released to the atmosphere. The other way is through burning fuels that are carbon-based.
Is phosphorus cycled through the earths atmosphere?
phosphorus is not cycled through the earth's atmosphere
How do forest control carbon dioxide in the atmosphere?
Through the process of respiration plants convert CO2 (carbon dioxide) into O2 (breathable oxygen).
How does carbon dioxide go back in the atmosphere?
Cellular respiration by producers and consumers returns carbon dioxide to the atmosphere.-Cellular respiration-Volcanic eruptions-Human interference (burning of fossil fuels)
During the carbon cycle in what form are carbon atoms generally returned to the atmosphere?
Carbon dioxide gas.
What is it called when carbon dioxide is returned to the atmosphere?
* combustion * respiration * oxidization * Retrixilization (rare)
How is carbon dioxide returned the atmosphere?
Cellular respiration by producers and consumers returns carbon dioxide to the atmosphere.-Cellular respiration-Volcanic eruptions-Human interference (burning of fossil fuels)
How is carbon dioxide returned to the. atmosphere?
Cellular respiration by producers and consumers returns carbon dioxide to the atmosphere.-Cellular respiration-Volcanic eruptions-Human interference (burning of fossil fuels)
How does carbon dioxide go back to the atmosphere?
Carbon dioxide goes back to the atmosphere through respiration, the decomposition of plants and animals, and combustion.
What are two ways in which carbon dioxide is added to the atmosphere?
Respiration by animals is one of the ways through which carbon dioxide is released to the atmosphere. The other way is through burning fuels that are carbon-based.
How do plants obtain carbon?
they obtain carbon by humans and organisms, etc.
Do cars omit carbon dioxide?
No, they release carbon and others from the exhaust but later the carbon goes through synthesis in which it forms carbon dioxide in the atmosphere.
How does carbon get into the atmosphere?
Carbon gets back into the atmosphere as carbon dioxide through the combustion of fossil fuels, and the cellular respiration of living things.
Which processes in the carbon cycle decreases the amount of carbon dioxide in the atmosphere?
Plants and trees remove carbon dioxide from the atmosphere through photosynthesis. The ocean also absorbs carbon dioxide, so much now that it is becoming more acidic.
Where does the leaf carbon dioxide?
From the atmosphere, of course. There is a small amount of carbon dioxide in the atmosphere and plants take in this gas through the stomata of their leaves and use it to construct sugars.
Through the process of photosynthesis plants?
absorb carbon dioxide from the atmosphere and store this carbon as sugar.
