What happens to oxygen level at high altitudes?
The oxygen level remains about the same, but the density of the air is reduced.
What happens to oxygen as the distance from the surface increases?
because there is less oxygen when you get closer to space the air is thinner, meaning oxygen will be harder to breathe at higher altitudes which can make you lack energy and become tired.
What happens to the oxygen level at high altitudes?
the oxygen level decreases
How is the air you breathe in different from the air we breathe out?
We get rid of waste when we breath out and when we breath in we take oxygen in to our lungs and breath.
How is the air you inhale or breathe in different then when you exhale or breathe out?
Inhaled air contains room air which contains oxygen. Exhaled air has carbon dioxide and, maybe, bad breath.
Is the oxygen less at high altitudes?
Yes. Air is less dense at higher altitudes, so the oxygen is at a lower concentration.
What causes thin air?
Thin air is caused by low oxygen pressure at high altitudes. The lack of oxygen makes the air less dense.
What happens to oxygen level at high altitudes?
The oxygen level remains about the same, but the density of the air is reduced.
Why did early pilots faint in the air?
lower oxygen levels in higher altitudes.
What is a sentence for the word altitudes?
Cloud structures vary at different altitudes due to different levels of air pressure. There are several scientifically recognized altitudes of atmosphere.
Why would you become short of breath at high altitudes if air at those levels still contain 21 oxygen?
Why would you become short of breath at high altitudes if air at those levels still contains 21% oxygen
Do high altitudes cause drowsiness?
High altitudes do cause drowsiness because there is less oxygen in the air, so you can't breathe normally.
What has air composition to do with why breathing at high altitude is difficult?
It is not so much as the composition that is important, it is that at higher altitudes there is less air. Air is about 20% oxygen, but the higher up you go in altitude, the thinner air will have less oxygen. That's what makes breathing more difficult at higher altitudes.
Do you find more oxygen in lower altitude?
yes because the air is more dense at lower altitudes
How has the mountain goats respiratory system adapted permantly to different altitudes?
The mountain goats respiratory system is adapted permanently to different altitudes. This is because it is the cellular respiratory system which allows it to survive the low oxygen climate.
How do you breathe in aeroplanes?
The oxygen at altitudes which airplanes fly is too low to support human life. Therefore air planes have air with oxygen which is circulated throughout the cabin for the passengers to breathe.
Why does atheletes who practice at higher altitudes experience lightheaded feeling?
Because there is less oxygen in the air at high altitude.
