the percentage of oxygen in the atmosphere today is about 20.95%. Or... if you round it you get the most common answer of 21%.
21% Oxygen, 78% Nitrogen, 1% other gasses in out atmosphere.
Oxygen is the component of the Earth's atmosphere that exists as a result of photosynthesis. During photosynthesis, plants and other photosynthetic organisms release oxygen as a byproduct. This process helps to replenish and maintain the oxygen levels in the atmosphere, supporting aerobic life forms.

During the Quaternary Period, oxygen levels in the atmosphere were similar to present-day levels, around 20.9%. This period saw the evolution and expansion of modern human species.
The most abundant compounds in Earth's atmosphere are nitrogen gas (N2) and oxygen gas (O2). Nitrogen makes up about 78% of the atmosphere, while oxygen comprises about 21%. Other gases like argon, carbon dioxide, and water vapor are present in much smaller amounts.

The atmosphere consists of about 20%, Nitrogen being the main component at over 70%
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.
Oxygen makes up about 21% of the Earth's atmosphere.
21% Oxygen, 78% Nitrogen, 1% other gasses in out atmosphere.
The atmosphere would be much more volatile.
Yes, there is oxygen present above the clouds in the Earth's atmosphere. The oxygen concentration gradually decreases with altitude, but it is still available for breathing.
Oxygen makes up about 21% of the Earth's atmosphere. Nitrogen is the most abundant component, making up approximately 78%.
The percent of oxygen is 27. this increases the natural percent of 21 by 6 percent causing living organisms to have too much oxygen.
Oxygen is the component of the Earth's atmosphere that exists as a result of photosynthesis. During photosynthesis, plants and other photosynthetic organisms release oxygen as a byproduct. This process helps to replenish and maintain the oxygen levels in the atmosphere, supporting aerobic life forms.
Assorted gases such as argon, the rest of the atmosphere is pretty much just Oxygen and Nitrogen.
