Which statement is not true of ozone? it forms a layer in the upper atmosphere. it produces ultraviolet radiation. it is a form of oxygen. it is an ingredient in smog.

The correct answer is B. It produces ultraviolet radiation.

Explanation:

Ozone (O3) is a molecule formed by three atoms of oxygen that forms a gas. Additionally, this gas forms a layer in the atmosphere known as the ozone layer that plays an important role because it absorbs almost all ultraviolet radiation from the sun. Indeed, the ozone layer and therefore ozone molecules can absorb around 98% of the UV radiation from the sun. This is also the reason why the destruction of ozone has important effects on Earth. This means the statement that is not true of ozone is "it produces ultraviolet radiation" because ozone absorbs this radiation instead of producing it.
