Question

Where is the ozone layer located?

Answer 1

Hint: Ozone is present naturally in the atmosphere. Ozone contains three oxygen atoms and to be denoted as $O_3$ . Ozone in the atmosphere was discovered by using optical and chemical methods. Ozone is a low relative abundance chemical in the atmosphere.

Complete step by step answer:
- The term ozone is derived from Greek word ozein meaning ‘to smell’.
- 90% of the ozone is present in the stratosphere.
- Stratosphere located 10- 16 kilometers on the earth’s surface and extended till 50 km.
- The part of the stratosphere which contains the highest amount of ozone is called ozone layer.
- The ozone layer is not restricted to one area on the earth, it is distributed throughout the globe with some variation in the concentration.
- The remaining 10% ozone is present in the troposphere which is located in between earth and stratosphere.

- Therefore the ozone layer is located in the stratosphere of the atmosphere.

Additional information:
- Ozone reacts with chemical substances rapidly and in high amounts it will be an explosive.
- Ozone gas has a pungent smell and we can detect it in very low amounts also.
- The structure of the ozone is as follows.

- The shape of the ozone is bent.
- Ozone is used in industries to purify water and air and is used as a bleaching agent in food and textile products.

Note: There are four layers in the atmosphere. They are the Troposphere, Stratosphere, Mesosphere, and thermosphere. Out of these four layers ozone is located in the stratosphere in the highest amount. The Stratosphere is located just above the troposphere on the earth’s surface.
