Approximately 2.4 billion years ago, during an event called the Great Oxidation Event, enough oxygen began accumulating in Earth's atmosphere due to the development of oxygen-producing photosynthetic organisms. This led to the rise of oxygen levels on Earth over time.

What keeps the oxygen inside earth?
Gravity is what keeps oxygen (and other gases) from escaping Earth's atmosphere. The gravitational force of Earth is strong enough to hold on to gases in its atmosphere, including oxygen. This allows for the maintenance of a stable and breathable atmosphere on the planet.
What percentage of the Earth's atmosphere is composed of oxygen?
About 21% of the Earth's atmosphere is composed of oxygen.
What percent of oxygen on the earth?
Oxygen makes up approximately 21% of the Earth's atmosphere.
What is percentage of oxygen in earth planet?
The Earth's atmosphere is composed of about 21% oxygen. This oxygen is crucial for supporting life on Earth through processes like respiration and photosynthesis.
Where does earth oxygen come from?
Earth's oxygen primarily comes from photosynthesis, a process where plants, algae, and some bacteria convert carbon dioxide into oxygen using sunlight. Around 50% of Earth's oxygen comes from the oceans, produced by marine plants like phytoplankton. Without these photosynthetic organisms, the Earth would not have enough oxygen to support animal life.

Why doesn't the moon have enough oxygen?
the reason the moon has not got enough oxygen is because the moon has no ozone layer so it has the same amount of air as the earth but it just escapes into the galaxy
Can you live anywhere besides earth?
Not at this time. Perhaps if enough oxygen and food were brought along.
How can earth sustain life?
The thick atmosphere has enough oxygen so than living things can happen.
Effects of no oxygen on earth?
Oxygen is main gas of earth. If there is no oxygen in the earth all the life in the earth should die.
What element will comprise earth's atmosphere hydrogen oxygen or nitrogen?
compromise? Hydrogen, if you could find enough to convert the oxygen into water. If you mean comprise then its 79 % nitrogen, 21 & oxygen, and 1% argon
How does the atmosphere keep oxygen inside?
Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
Why do you breathe on earth but not on any other planet?
There isn't any oxygen, or plants to create it..Because other planets do not have the righ gases. Earth has enough O2 to breath.
Where on the planet can you find oxygen?
oxygen is everywhere on earth, there are times where there is so little oxygen that it is unnoticed like in water there are 2 hydrogen molecules but 1 oxygen molecule so there is nowhere near enough oxygen. when you go up a mountain you are getting farther from the inhabitable area of the Earth's atmosphere and there is less and less oxygen. Fire is fueled by oxygen, but will not egnite if in a confined space because it would use up any oxygen.
How come only earth has enough air to live on?
because the other planets have different temperatures and do not contain enough Oxygen. I think :P BECAUSE GOD CREATED IT THIS WAY!
Can not getting enough oxygen make you sleepy?
Yes, not getting enough oxygen can and will make you drowsy, also, not getting enough oxygen can cause brain damage. - Heisenberg
Where do you get your oxygen on earth?
we get oxygen from the trees
