Questions :
Which layer of the atmosphere contains the ozone layer?
Options :
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
correct answer : b)
Explanation :
The troposphere is the lowest layer of the atmosphere where weather activities take place, but it does not contain the ozone layer. The stratosphere is the correct answer because the ozone layer is located in this layer and it protects life on Earth by absorbing harmful ultraviolet rays from the Sun. The mesosphere lies above the stratosphere and is mainly known for the burning of meteors. The thermosphere is the uppermost layer with extremely high temperatures and has no significant concentration of ozone.
