Question

Compare the contrast the roles of ozone$\mathbf{\left(}{\mathbf{\text{O}}}_{\mathbf{3}}\mathbf{\right)}$and nitrogen dioxide in stratosphere and in the troposphere.

Short answer

The difference between stratospheric and tropospheric ozone is that stratospheric ozone concentrations are extremely high, whereas tropospheric ozone concentrations are extremely low.

Step-by-step solution

Role of ozone in Stratosphere

Ozone in the stratosphere is a naturally occurring gas that filters ultraviolet (UV) radiation from the sun.

Because it minimizes the detrimental effects of ultraviolet (UV-B) light, this is commonly referred to as "good" ozone.

More radiation penetrates the Earth's surface when the ozone layer depletes.

Role of ozone in the Troposphere

Tropospheric ozone is a highly reactive oxidant that lowers agricultural yield and vegetation's ability to absorb atmospheric carbon. Plants suffer from stunted growth and seed production, as well as diminished useful leaf area and rapid aging.

Step 3: The contrast of the roles of ozone and nitrogen dioxide in the stratosphere and in the troposphere.

The main distinction between stratospheric and tropospheric ozone is that stratospheric ozone concentrations are extremely high, whilst tropospheric ozone concentrations are extremely low.

Furthermore, by observing the generation of ozone gas, one can distinguish stratospheric ozone from tropospheric ozone.

The interaction of atomic oxygen with molecular oxygen produces ozone gas in the stratosphere. In the troposphere, however, ozone gas is formed by the interaction of nitrogen oxides with volatile organic molecules in the presence of sunlight.
