How long does co2 remain in the atmosphere
What evidence is there that plants make there own food using energy from the Sun?
The process called photosynthesis takes carbon dioxide from the atmosphere and energy from the Sun's rays to separate out carbon and oxygen. The carbon is used to form the long organic molecules that make up the body of the plant, while the oxygen is mainly released back into the atmosphere. That's how we have oxygen to breathe, and without plants mammal life would never have been possible. Later the plant tissue (e.g. wood) can be burned, and this reunites the carbon and oxygen atoms to produce heat and carbon dioxide. This can also happen after millions of years after the plants have decomposd and fossilised, and this is the origin of the term 'fossil fuel'.
How long has oxygen been fully present in the atmosphere?
500 million years
Do the percentages of gases in your atmosphere change?
Over long periods of time the concentrations of some gasses such as oxygen and carbon dioxide do change. Water vapor is even more variable, often changing on a daily or hourly basis.
Can you breathe on Mars?
It's not possible to breathe on Mars without a spacesuit because the atmosphere is mostly carbon dioxide with extremely low levels of oxygen. Without proper equipment, it would be fatal to breathe the Martian atmosphere.
Why aren't we running out of oxygen in the atmosphere?
Oxygen in the atmosphere is constantly being replenished through photosynthesis by plants and marine algae. These organisms convert carbon dioxide into oxygen as a byproduct of their metabolic processes. As long as these processes continue, oxygen levels in the atmosphere will be maintained.

Is there carbon in the earths atmosphere?
yes. carbon monoxide is one carbon and one oxygen carbon dioxide is one carbon and two oxygens methane is one carbon and 4 hydrogens any hydrocarbon is a long chain of carbon and hydrogen there are many other forms
What two sources take CO2 out of the atmosphere?
The ocean removes carbon dioxide (CO2) from the atmosphere as part of the carbon cycle. This carbon recycles round and returns to the atmosphere again.Trees, forests and all growing vegetation remove CO2 from the atmosphere, release the oxygen, and store the carbon. If it is a long living tree, it can store that carbon for hundreds of years.
Will the amount of carbon dioxide in the atmosphere soon be greater than the amount of oxygen?
Hahaha! No, never. Oxygen is around 19 or 20% of the air, Carbon Dioxide is about 0.00 something percent. It's a small amount but it's enough to cause the greenhouse effect. If it ever did, we'd be long dead/overheated. So, yeah, it never will.
How is oxygen kept in the atmosphere?
Physically kept there? By gravity, same as all other atmospheric gases.Chemically kept there in spite of its reactive nature? It's not, really. Atmospheric oxygen readily reacts chemically with other substances all the time. However, plants are continually pumping new oxygen into the atmosphere via photosynthesis in opposition to that trend, and the two processes roughly cancel each other out. (Or did, before combustion of fossil fuels started increasing carbon dioxide concentrations since the dawn of the industrial era.)If it weren't for photosynthesis, a reactive gas like oxygen would not long remain a component of the Earth's atmosphere.
What processes remove it from the atmosphere?
Plants photosynthesize and absorb carbon dioxide from the atmosphere, converting it into oxygen and biomass. Ocean uptake is another important process where carbon dioxide dissolves into the seawater. Additionally, chemical weathering of rocks and minerals over long periods of time also helps in removing carbon dioxide.
How long has the oxygen concentration of the atmosphere been at its current level?
The current oxygen concentration in the Earth's atmosphere has been relatively stable at around 21% for the past 300 million years. This level is maintained through processes like photosynthesis by plants and phytoplankton, which convert carbon dioxide into oxygen.
How long does carbon remain in some stages of the cycle?
because
Why does the atmosphere's composition remain stable?
The Earth's atmosphere is stable because is mostly oxygen and nitrogen. These two parts of the atmosphere are equal to about 99% of all dry air gas. Water vapor accounts for negligible amounts. While the composition of water vapor, carbon dioxide and ozone can vary in concentration, all other elements remain stable.
How long ago did the atmosphere on earth have the most carbon dioxide?
The atmosphere on Earth had the most carbon dioxide around 300 million years ago during the Carboniferous period. This period is known for high levels of atmospheric carbon dioxide which supported the growth of lush forests and high oxygen levels.
Where does oxygen comes from?
Oxygen is chemically released through photosynthesis in green plants. The atoms of oxygen, however, were created in the cores of stars that exploded long before our Solar System began to form
