Question

Even though ground-level ozone is a health hazard, the ozone layer in the stratosphere is a health benefit because

Answer 1

The ozone layer absorbs a large portion of incoming UV radiation, which 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. Ozone is a pollutant in the troposphere. By regulating the amount of UV radiation that enters the troposphere, the ozone layer also regulates the amount of ozone formation in the troposphere.

Step-by-step explanation:

Answer 2

Basically a health benefit would be that the ozone layer along with the oxygen molecules found in the stratosphere, absorb the ultraviolet rays emitted from the sun thus providing a shield that prevents radiation.
