Q. Which of the following statements concerning atmosphere of the Earth are correct?
1. In stratosphere, temperature increases with altitude.
2. In mesosphere, temperature decreases with altitude.
3. The lowest temperature of the atmosphere is recorded in the upper part of mesosphere.
4. Tropopause is an isothermal zone.
Select the correct answer using the code given below.

Explanation by: Admin

In stratosphere, temperature increases with altitude.

This is true because the ozone layer in the stratosphere absorbs UV radiation, causing temperature to rise with altitude.

In mesosphere, temperature decreases with altitude.

Correct. The mesosphere is cooler as you go higher, reaching some of the coldest temperatures in the atmosphere.

The lowest temperature of the atmosphere is recorded in the upper part of mesosphere.

Tropopause is an isothermal zone.

Correct. The tropopause acts as a boundary between the troposphere and stratosphere, where temperature remains nearly constant with altitude (isothermal).

All four statements are correct, so the answer is (D).
