Question

How is the ozone formed in the higher level of atmosphere? Explain?

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 molecule to form ozone

Answer 2

Answer:

Answer:

1. Ozone is a gas formed by 3 atoms of oxygen.
2. It is formed at higher levels of atmosphere.

• The high energy UV rays split some molecules of oxygen into free oxygen atoms. These atoms are very reactive and combine with molecular oxygen present in the atmosphere to form ozone. The chemical reaction is given below
• $O_{2}$ + UV radiations -------> [O] + [O]
• [O] + $O_{2}$ ------------> $O_{3}$

In this way ozone is formed at higher levels of atmosphere.
