Question

a temperature inversion forms when warm air forms a \cap\ on top of the cold air below it. which pollutant often gets \stuck\ below a temperature inversion? tropospheric (ground level) ozone hydrogen gas

Explanation:

Temperature inversions trap pollutants near the ground. Tropospheric (ground - level) ozone is a pollutant formed from reactions of pollutants like NOₓ and VOCs in the lower atmosphere. In a temperature inversion, the warm air above prevents it from rising, so it gets stuck. Hydrogen gas is not a typical pollutant trapped in this way as it is light and can escape or isn't a common ground - level pollutant in the context of inversion trapping.

Answer:

tropospheric (ground level) ozone
