Where did the oxygen and ozone in your atmosphere come from according to this theory?

Oxygen when came in contact with UV broke down. It then reacted with more oxygen to form ozone.


Is the ozone in the atmosphere a form of carbon?

No its not. Ozone is a form of oxygen.


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.


Why id pzone an important form of oxygen?

Ozone is an important form of oxygen. It forms a miracle layer in atmosphere.


What has the most oxygen in it?

The oxygen molecule, the form of oxygen found in the Earth's atmosphere, is 100% oxygen. There fore it is the material that has the most oxygen in it.


A gas that is a form of oxygen which created a layer of gas in the upper atmosphere?

A gas that forms oxygen is ozone. It is the one present in the upper atmosphere.


Will there be oxygen in space if you plant a tree there?

Interesting question. The Oxygen must come from somewhere. On Earth a plant gets oxygen from 2 sources. Water and/or the atmosphere. It does not just make it up, simply transforms it from one form to another. A plant takes in Carbon Dioxide (CO2) and releases the Oxygen (O2) into the atmosphere. If there were some form of atmosphere/light/water to sustain the plants life then they will automatically produce a more oxygen rich atmosphere. As for the moon: It doesn't really have enough gravitational pull to sustain an atmosphere like that. Maybe Mars where the Atmosphere is 95% Carbon Dioxide and quite possibly large frozen lakes of ice.


Which layer of atmosphere keeps in oxygen?

Troposphere keeps in most of the oxygen in it. Ozone, a form of oxygen is kept in stratosphere.


Which gases form the atmosphere?

oxygen, nitrogen, hydrogen, and carbon dioxyde


Describe the significance of cyanobacteria in the formation of earth's atmosphere?

cyanobacteria also called blue-green algae is thought to be one of the first ever photosynthetic organism...prior to the evolution of photosynthetic organisms theoxygen percentage of the atmosphere was 0% and as we all know without oxygen (O2), ozone(O3) cannot form, and without ozone there can be no atmosphere. Photosynthetic organisms allowed for the formation of oxygen and brought oxygen levels to the percentage it is today (20% a significant increase from 0%) as a result ozone was able to form and ultimately the atmosphere emerged.


When hydrogen and oxygen are mixed they form water then why exist in gaseous form?

very high temperature is needed to combine hydrogen and oxygen. at that temperature, water exists in gaseous form Oxygen exists as a gas in our atmosphere, because there isn't very much hydrogen in the atmosphere. If the Earth's atmosphere contained a substantial amount of hydrogen mixed with the oxygen, it would be an explosive mixture. Any spark would set it off. They the oxygen and hydrogen would combine to form water, and we would be left without enough oxygen to breathe.


What kind form of oxygen which protect atmosphere who protect harmful solar radiations?

Ozone is the type of oxygen which protects us from the harmful solar radiations. It is the triatomic form of oxygen.
