Short Answer: UV-C from the Sun is absorbed by the oxygen up high, and that allows ozone to be made up high. Ozone decays back to oxygen before it can fall very far... Ozone is not the heaviest gas, iodine heptafluoride (for example) is much heavier. Ozone is heavier than other gases commonly found in the atmosphere... Ozone is present in all layers of the atmosphere. It is concentrated in the stratosphere (which is not the "top of the atmosphere" there are more layers above it), because almost all the UV-C from the Sun is stopped there by oxygen and nitrogen, where the atmosphere's density starts really going up. Oxygen molecules broken into atoms, can yield the production of some ozone, monatomic oxygen is very short lived, so ozone is formed very quickly or not at all. As you move lower in the atmosphere, water vapor (and other contaminants) rapidly destroy ozone, so this allows ozone concentrations to decrease to near zero at Earth's surface. Oxygen molecules are broken apart by 215nm or shorter UV light (UV-C). So are nitrogen, and other atmospheric constituents. So beyond a certain depth into the atmosphere, there is insufficient 215nm or shorter light to break oxygen which can then make ozone. Then it takes a very long time (months) for gasses to diffuse in quantity large distances vertically, and ozone gas does degrade with time... so it appears this heavy gas hovers high above us. When in fact it is created, and disppears before it can fall very far.
What else can I help you with?
What does the layer in the upper atmosphere do?
The layer in upper atmosphere is ozone layer. It protects us from UV rays of the sun.
A gas that is a form of oxygen which created a layer of gas in the upper atmosphere?
Ozone is a gas form of oxygen that is found in the Earth's upper atmosphere. It forms a layer known as the ozone layer, which plays a crucial role in protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet radiation.
Why is ozone found in upper atmosphere not a pollutant?
The ozone found in the upper atmosphere protects us from the UV rays. It is not a polluntant.
What is a layer of gas contained in the upper atmosphere?
The layer of gas contained in the upper atmosphere is called the ozone layer. It is important for protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet radiation.
Is is true that ozone collects in a layer in the upper atmosphere?
Yes, ozone does collect in a layer in the upper atmosphere known as the ozone layer, located in the stratosphere. This layer plays a crucial role in filtering out harmful ultraviolet radiation from the sun, protecting life on Earth.
Why is it a good thing for the ozone layer to be in the upper atmosphere?
It is a good thing for the ozone to be in the upper atmosphere. It is due to the fact that ozone in upper atmosphere forms the ozone layer.
In the upper layer of the atmosphare ozone is formed by?
The upper layer of the atmosphere is formed by ozone layer. This is a layer of ozone gas.
What does the layer in the upper atmosphere do?
The layer in upper atmosphere is ozone layer. It protects us from UV rays of the sun.
Why is ozone found in upper atmosphere and not on earth Give reasons and also give uses of ozonesuggest method to prevent ozone depletion and consequenses if we don't care?
The ozone layer is found in the upper atmosphere. It is because of the suitable conditions there.
What is the layer of gas contained in upper atmosphere?
Ozone layer

The ozone layer is located in the upper region of the what?
The atmosphere ofcourse!
How are cfcs in the upper atmosphere related to the ozone layer?
They are carried by westerlies. They destroy the ozone.

In the upper layer of the atmosphere ozone is formed?
Ozone is formed by UV rays. They are rays from the sun.
