No it doesn't. It contains ozone.
No it is not. Oxygen is the one that creates the ozone layer.
Atmosphere does contain many layers. A layer that helps in stratosphere is ozone.
No oxygen is not a danger to ozone layer in stratosphere. It is because oxygen itself participates in the creation of ozone.
None
The stratosphere is the second layer of Earth's atmosphere and contains 15% of the mass found in Earth's atmosphere. The ozone can be found in the stratosphere. What you won't find there are planes and clouds.
Ozone is maintained in stratosphere. It is because of UV rays.
The troposphere has more volume of oxygen compared to the stratosphere. This is because the troposphere is the layer of the atmosphere closest to the Earth's surface, where most atmospheric gases are concentrated, including oxygen. The stratosphere, located above the troposphere, has lower concentrations of oxygen.
The ozone appears in the stratosphere and troposphere. Lower stratosphere and higher troposphere contain it.
nitrogen and oxygen
The normal atmospheric gases, at low pressure.
Individuals of oxygen are formed in the stratosphere when oxygen molecules that consist of two oxygen atoms are striked by ultraviolet light.
We know that oxygen is just a bit heavier than the air like carbon dioxide ,nitrogen etc.Besides that the main source of oxygen,the trees is in troposphere. Because of this reasons oxygen density is much heavier in troposphere than the stratosphere
