Around 90% of all the ozone contained in the atmosphere is accumulated in the stratosphere - this area is also called the ozone layer due to the high concentration of ozone.
Troposphere is below the stratosphere, and it's the one that's closest to the earth.
Answer:
The ozone layer absorbs a large portion of incoming UV radiation.
Explanation:
This means it keeps ground-level ozone from forming. A higher percentage of UV radiation entering the troposphere would allow a greater amount of ozone to form in the troposphere.
