Because they are interested in whether water vapor, ozone or oxygen in a plants atmosphere are there.
The form of oxygen you are referring to is called ozone, and it is a unstable triatomic molecule, which, when in the lower atmosphere, acts as a pollutant, damaging the respiratory system of animals, and burning sensitive plants. If it is in the upper atmosphere, however, it is extremely beneficial, as it prevents dangerous UV rays from getting to the earth.
A free radical. A gas. A photochemical product. Oxygen.
earth, specifically the atmosphere
You are thinking of ozone.
They were already present in nature. They were just discovered by scientists.
Ozone is not an atom, but a molecule containing 3 Oxygen atoms. In the lower atmosphere, it is harmful to plants an animals, but it is beneficial in the upper atmosphere, as it protects Earth from ultraviolet radiation.
No its not. Ozone is a form of oxygen.
The oxygen formed in upper atmosphere is not for breathing. It forms again into ozone by natural phenomenons.

Ozone is an isotope of oxygen. It is present as the ozone layer in the atmosphere.
The continual interchange of oxygen between the atmosphere and the water, the plants and animals and mineral matter is called the oxygen cycle.
Green plants produce oxygen. Free oxygen can, under specific circumstances, combine to form ozone. Sufficient concentrations of ozone in the upper atmosphere can block a portion of the Sun's UV radiation.
Oxygen in the atmosphere is O2, two atoms of oxygen. Ozone, no matter where it is in the atmosphere or in a process, is O3, three atoms of oxygen.
Ozone is present in the stratosphere of the earth's atmosphere. It is in this region that the scientists are concerned.
CFC's are released into atmosphere. They break the ozone into oxygen molecules.
Most of the xygen is emitted by plants as a by product of photosynthesis. Some oxygen comes from phytoplankton in the oceans and some enters the atmosphere when sunlight breaks down water
Oxygen cycle is at ground level. Ozone layer is in atmosphere.
