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 are the most abundant element s in the atmosphere?
The air (on ground level, not in a traffic jam!) is composed of ~80% N2, ~20% O2, 0-6% H2O (vary a lot), 0.03% CO2, 1% argon and then traces of other elements. The most abundant element is thus nitrogen N.
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.
What is the most prevalent atom in air?
I assume you mean which air molecule makes up the largest percentage in the Earth's atmosphere. Nitrogen makes up about 78% of the Earth's atmosphere at our (liveable) level, and next is oxygen at about 21%. The other 1% is composed of carbon dioxide, argon and other gases.
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.

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.

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.
Why has the nitrogen level in the atmosphere kept constant over time?
The absolute amount of nitrogen in the atmosphere has kept constant over time because it is not a gas that reacts readily with other elements - it is relatively inert. However, the relative level of nitrogen in Earth's atmosphere has changed over time as the atmosphere was "terraformed" by the life evolving on the planet. For instance in the Cretaceous times the atmosphere was much richer in Oxygen (30%) than today (20%) which means that then the %Nitrogen was 70% rather than 80%.
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.
What is the volume of nitrogen in the earths atmosphere at sea level?
The volume of nitrogen in Earth's atmosphere is approximately 78% of the total volume at sea level, which is roughly 78.08%. The volume of nitrogen is expressed as a percentage of the total volume of gases in the atmosphere.
What is an oxygen enriched environment?
Air is the mixture of gases that surrounds the Earth. The composition of the earth's atmosphere varies with altitude, but at sea level contains approximately 78% nitrogen and 21% oxygen by volume.An oxygen-deficient atmosphere contains less than 19.5% oxygen by volume.An oxygen-enriched atmosphere contains more than 23.5% oxygen by volume.
What is the role of nitrogen-fixing bacteria?
they help balance the level of nitrogen in the soil and atmosphere.
