Question

By which layer of the atmosphere the ultra-violet rays are absorbed ?
1. Troposphere
2. Ionosphere
3. Exosphere
4. Ozonosphere

Answer 1

Correct Answer - Option 4 : Ozonosphere

The correct answer is Ozonesphere.

• The ozonosphere or Ozone layer is part of the Stratosphere.
• The ozone layer in the stratosphere is the layer by which ultra-violet rays are absorbed.
• It is the lowest layer of the Stratosphere which is 15-25 km above the Earth's surface.
• It contains a high concentration of ozone molecules (O₃).

 Thus, we can say that Ozonosphere absorbs the ultra-violet rays.

•  Our atmosphere is divided into five layers:
  • Troposphere
  • Stratosphere
  • Mesosphere
  • Thermosphere
  • Exosphere
