Question

where do we want ozone?

in the troposphere

in the lithosphere

in all our homes

in the stratosphere

Explanation:

Ozone in the stratosphere forms the ozone layer, which absorbs harmful ultraviolet (UV) radiation from the sun, protecting life on Earth. Ozone in the troposphere (ground - level ozone) is a pollutant that can harm human health and the environment. The lithosphere is the rigid outer part of the Earth (rocky layer) and is not a place where we "want" ozone in the context of its beneficial role. Ozone in homes can be harmful as it is a respiratory irritant.

Answer:

in the stratosphere
