∙ 9y agoOne cause why oxygen is found at atmosphere is the presence of water. The atmosphere is made up of different gases with oxygen being one of the main gases.

How does fertilizer running into a pond lower the oxygen level?
The fertilizer causes an increase in algae. As algae die and are decomposed the decomposers increase and use up all of the oxygen in the water.
What is the Level of oxygen on Saturn?
There is oxygen in the atmosphere of Saturn, but it is only a tiny fraction of the deep atmosphere, which is mostly hydrogen. It is not in a usable form as is oxygen on Earth.
Which part of the oxygen cycle can damage the ozone layer?
Oxygen cycle is at ground level. Ozone layer is in atmosphere.
Is there oxyen on Mars?
There is a very small amount of oxygen on Mars. The oxygen level in Marsâ?? atmosphere said to be around .145%.
What happens when higher energy UV radiations act on the oxygen at the higher level of the atmosphere?
ozone layer prevents harmful UV radiations to reach earth's atmosphere. ozone is formed at the higher level of atmosphere by the action of UV radiation on molecule. High energy UV radiations split apart some oxygen molecules into atomic oxygen which react with molecular oxygen to form ozone molecules.
How do you increase oxygen level in atmosphere?
don't smoke, excercise, espessially walking.
How does fertilizer running into a pond lower the oxygen level?
The fertilizer causes an increase in algae. As algae die and are decomposed the decomposers increase and use up all of the oxygen in the water.
Is oxygen part of the atmosphere?
Yes, molecular oxygen makes up about 20% of the atmosphere at sea level.
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 would Earth's atmosphere be like today if life had not evolved on Earth?
It might be similar to the atmosphere on Venus, where the oxygen has combined with surface rocks and as carbon dioxide. On Earth, plants remove carbon dioxide and increase the level of free oxygen that supports animal life. This atmosphere also reduces ultraviolet radiation, which also affects the level of gases.
What happen when higher energy ultraviolet radiations act on the oxygen at the higher level of the atmosphere?
when higher energy ultraviolet radiation act on the oxygen at the higher level of the atmosphere, they destroying many molecules of atmosphere.
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 is the Level of oxygen on Saturn?
There is oxygen in the atmosphere of Saturn, but it is only a tiny fraction of the deep atmosphere, which is mostly hydrogen. It is not in a usable form as is oxygen on Earth.
Atmosphere in the permian?
the atmosphere in the Permian had 115 % of modern oxygen level and 3x the amount of carbon dioxide- pre-industrial level.
Does the troposphere have oxygen?
Oh yes. The troposphere is the lowest level of the atmosphere, the level that we live and breathe in, and it does have lots of oxygen in it, until you get to very high altitudes.
Where in atmosphere does meteoroids burn?
"where the oxygen level increases then combustion takes place"
What is the percentage of oxygen in Saudi Arabia?
At sea level everywhere on the Earth oxygen makes up about 20% of the atmosphere.
