The UAE is on the coast, so the answer is the same as the rest of the world (at the coast), about 21%
Air is approximately 20% Oxygen.
UAE regarded as an important location in air transport.
Oxygen - yes. Air - no. Not much of that around underwater.
No.
The Earth's atmosphere is composed of roughly 21% oxygen. This level of oxygen in the air is ideal for human respiratory needs.
About 20% of the volume of the air in the room is oxygen.
Around 16% of the air you breathe out is oxygen. This percentage decreases from the 21% of oxygen in the air you inhale due to the exchange of gases that occurs during respiration.
A small percent . exhaled air always contains oxygen .
Concentration of oxygen in dry air is 20,946 %.
ideally 21% (20.95%)
Oxygen, of course.
The concentration of oxygen in the air is much much higher than in the water. This make obtaining oxygen much easier and strenuous activity (to a level higher than that is water) possible.
