When will the Earth run out of oxygen?

The Earth will not run out of oxygen anytime soon. Oxygen is constantly being produced by plants through photosynthesis, and there is currently enough oxygen in the atmosphere to support life for millions of years.

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 percentage of oxygen is present in the Earth's atmosphere?

About 21 of the Earth's atmosphere is made up of oxygen.
