How long has the oxygen concentration of the atmosphere been at its current level?
The oxygen concentration in the atmosphere today (which is at about 21%) has been at its current level for the past 400 million years.
What gas is composed of the three atoms of oxygen and occurs both in the upper atmosphere of the earth and at ground level?
That is ozone.
What gas is composed of three atoms of oxygen and occurs both in the upper atmosphere of earth and ground level?
its ozone to be truthfully :)
What happens to the oxygen level at high altitudes?
the oxygen level decreases
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
What is the role of biosphere in forming the current level of atmospheric oxygen?
Biosphere is the sphere in which the human beings survive. It is something that creates ozone naturally.
Is 24 percent oxygen considered a normal occurrence?
No, 20% oxygen is the normal atmospheric level.
What is the partial pressure of oxygen on Mt Everest if the atmospheric pressure on Mt Everest is one-third the atmospheric pressure at sea level?
It will be same as it is at sea level.
How long has the oxygen concentration of the atmosphere been at its current level?
The oxygen concentration in the atmosphere today (which is at about 21%) has been at its current level for the past 400 million years.
Does atmospheric pressure have any effect on the oxygen level in the scuba tank?
No, only when it is released into the atmosphere at the ambient pressure.
How much oxygen is available 5.5 kilometers above sea level?
From sea level to an altitude of 300 meters there is enough oxygen. After 300 meters of altitude, there is enough oxygen. 4500 meters to 4800 meters of altitude and low atmospheric pressure due to lack of oxygen to human breath.
How can ozone be both good plus bad for life on earth?
Ozone is good at atmospheric level. It is bad at ground level as pollutant.
Which is different from the ozone layer of the earth?
The ozone layer of the earth is a very protective and important layer. This layer is a boon at the atmospheric level.
What is atmospheric pressure of oxygen at an elevation of 20000 ft above sea level?
The atmosperic pressure would be about 370 millibar
How does the atmospheric pressure at altitudes sea level compare with atmospheric pressure at sea level?
the atmospheric pressure below sea level is highter (novanet)
What gas is both harmful and beneficial to life on Earth?
CO2, Oxygen, Nitrogen, Ozone. Water vapour
Why is pressure on mounteverest?
bcoz when u go higher from the earth's surface the oxygen level decreases. we know that earth has a strong layer that is atmosphere so it has a level where it ends so if u go more further the oxygen level decreases!!!
