Question

ozone in the stratosphere forms the ozone layer and is beneficial. where is ozone a pollutant? mantle troposphere

Explanation:

Ozone in the stratosphere (ozone layer) is beneficial as it absorbs UV radiation. However, in the troposphere (the lowest layer of Earth's atmosphere, where we live), ozone is a pollutant. It is formed from pollutants like nitrogen oxides and volatile organic compounds reacting in sunlight, and it can cause respiratory issues, damage crops, and harm ecosystems. The mantle is part of Earth's interior and not a region where ozone (a gaseous substance related to atmospheric chemistry) would be a pollutant.

Answer:

Troposphere
