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.
Answer & Explanation
Answer: D) 1, 2, 3 and 4
Explanation: In troposphere and mesosphere, temperature declines with increasing altitude. In stratosphere and thermosphere, temperature increases with increasing altitude.The coldest temperatures in Earth’s atmosphere occur at the top of mesosphere, the Mesopause, especially in the summer near the pole.Transitional layers of atmosphere include tropopause, stratopause, and mesopause. These layers are relatively thin and are located between major layers of atmosphere. These have contrasting thermal properties. Hence, in these layers there is no change in temperature with change in altitude.
