What else can I help you with?
Is oxygen part of the atmosphere?
Yes, molecular oxygen makes up about 20% of the atmosphere at sea level.
What is the oxygen level o the moon?
The Moon has an extremely thin atmosphere, known as an exosphere, which contains trace amounts of oxygen. The oxygen level is less than 0.0001% of the lunar atmosphere, making it virtually negligible for sustaining human life or any known form of respiration. Most of the Moon's surface is composed of oxygen-rich minerals, but free molecular oxygen is not present in significant quantities.
What is the density of the atmosphere?
The density of the Earth's atmosphere varies with altitude, but at sea level it is approximately 1.2 kg/m^3. As you move higher in the atmosphere, the density decreases.
What are the main ingredients in the atmosphere?
The air we breathe near sea level is approximately 78% nitrogen, 21% oxygen, and 1% other. The exact composition changes at different levels in the atmosphere.
Auroras are caused by what hitting the atmosphere?
Auroras are caused by charged solar particles colliding with atoms of oxygen and nitrogen in the ionosphere, which is the highest level of the atmosphere.
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.
What happens when higher energy ultraviolet radiations act on the oxygen at the higher level of the atmosphere?
formation of ozone
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 happen when higher energy ultraviolet radiations act on the oxygen at the higher level of the atmosphere?
When higher energy ultraviolet radiations act on oxygen at higher levels of the atmosphere, they can break apart oxygen molecules (O2) into two individual oxygen atoms. These oxygen atoms can then combine with other oxygen molecules to form ozone (O3) through a series of reactions. This process is important for the formation of the ozone layer, which helps protect Earth from harmful UV radiation.
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 is there more oxygen available to breath at sea level than there is higher in the atmosphere?
At sea level, the atmospheric pressure is higher, which compresses the air and allows more oxygen molecules to be present in each breath. As you go higher in the atmosphere, the air pressure decreases, reducing the density of oxygen and making it harder to breathe in enough oxygen with each breath.
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!!!
Atmosphere in the permian?
During the Permian period (~299 to 252 million years ago), the Earth's atmosphere had higher concentrations of oxygen compared to today, around 30%. This higher oxygen level supported the evolution of large insects and reptiles during this era. Additionally, the climate was generally warmer, with significant fluctuations that led to the formation of vast inland seas and arid regions.
What happens to the oxygen level at high altitudes?
At high altitudes, the oxygen level decreases because the air is less dense. As you ascend to higher altitudes, the air pressure drops, resulting in lower oxygen levels in the atmosphere. This can lead to symptoms of hypoxia and altitude sickness in individuals who are not acclimated to such conditions.
An oxygen deficient atmosphere has an oxygen concentration less than?
An oxygen deficient atmosphere has an oxygen concentration less than the normal level of around 21%.
What Percent oxygen at 10000feet altitude?
At 10,000 feet altitude, the percentage of oxygen in the atmosphere remains the same as at sea level, which is about 21%. However, the partial pressure of oxygen decreases at higher altitudes, leading to lower oxygen levels available for breathing.
At what altitude do you need bottled oxygen?
The higher into the atmosphere the plane ascends, the thinner the air is. This is the reason oxygen is required. The United States Parachute Association states oxygen use should begin at 15,000' above ground level.
