Question

What is ozone? How is it formed at the higher levels of atmospheres?

Answer 1

Answer:

The ozone layer is continuously formed in the atmosphere because of the action of UV rays on molecular oxygen. The high-energy UV radiations break down O2 molecules present in upper layers of the atmosphere into nascent oxygen. Then, this free oxygen atom combines with an oxygen .

Answer 2

Ozone, or trioxygen, is an inorganic molecule with the chemical formula O 3.

It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2 (dioxygen). Ozone is formed from dioxygen by the action of ultraviolet light (UV) and electrical discharges within the Earth's atmosphere.
