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.
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.
About 21% of the Earth's atmosphere is composed of oxygen.
Oxygen makes up approximately 21% of the Earth's atmosphere.
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.
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.

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
Not at this time. Perhaps if enough oxygen and food were brought along.
The thick atmosphere has enough oxygen so than living things can happen.
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
Oxygen is main gas of earth. If there is no oxygen in the earth all the life in the earth should die.
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).
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.
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.
because the other planets have different temperatures and do not contain enough Oxygen. I think :P BECAUSE GOD CREATED IT THIS WAY!
Earth is the only planet in our solar system known to have abundant oxygen in its atmosphere, making it suitable for sustaining life as we know it. Other planets such as Mars and Venus have trace amounts of oxygen but not enough to support human life without additional life support systems.
Yes, not getting enough oxygen can and will make you drowsy, also, not getting enough oxygen can cause brain damage. - Heisenberg
