Oxygen began to accumulate in Earth's atmosphere approximately 2.4 billion years ago during the Great Oxidation Event, brought about by the emergence of photosynthetic organisms that produced oxygen as a byproduct of photosynthesis.
Earth's atmosphere is about 21% oxygen by volume (for dry air).
My atmosphere is the same as your atmosphere since we all live on the same planet. Oxygen makes up about 19.5% of the atmosphere.
Yes, there is oxygen in the atmosphere of Mars, but it is present in very low concentrations, about 0.13%. This is much lower compared to Earth's atmosphere, which is around 21% oxygen.
There is approximately 21 % oxygen in our air.
The component of the atmosphere that causes iron to rust and paint to dull is oxygen. When iron is exposed to oxygen and moisture, a chemical reaction called oxidation occurs, leading to the formation of iron oxide, or rust. In the case of paint, oxygen can react with components of the paint, causing it to lose its shine and appear dull over time.
21% of the atmosphere is oxygen.
The atmosphere is 79.9% oxygen.
the environment which has the availability of oxygen it is called aerobic atmosphere and if the availability of oxygen is not there in atmosphere then it is anaerobic type We live in a aerobic atmosphere which has the oxygen available
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
About 21% of the Earth's atmosphere is oxygen.
Plankton gives more oxygen to the atmosphere.
Animals remove oxygen from the atmosphere.
Yes, oxygen makes up 20.9% of the atmosphere.
Cyanobacteria make molecular oxygen in our atmosphere.
Earth's atmosphere is about 21% oxygen by volume (for dry air).
The two major components of the earth's atmosphere are nitrogen and oxygen. There is also trace amounts of hydrogen, carbon dioxide, and other gases.
No it isn't. We still have about 21% oxygen content in the atmosphere.
