Why Is Ozone Layer Formed in Stratosphere

Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.

Why is the ozone layer forming the stratosphere instead of troposphere?

Within the so-called “ozone hole,” levels can drop to 85 DU. … CFCs are transported to the stratosphere by this process, which also allows ozone exchange between the atmospheric levels. The net transfer of ozone is from the stratosphere to the troposphere, because of the higher levels of ozone in the upper level.

What is the function of ozone in the upper stratosphere?

The Ozone layer at the upper atmosphere perform the function of absorbing the harmful ultra violet (UV) rays coming from sun and prevents them from reaching the earth. These UV rays cause harmful effects to humans, animals and plants.
