Which one of the following statements about temperature is correct?

  • A
    Temperature decreases with height in the stratosphere.
  • B
    Temperature is constant at different heights in the stratosphere.
  • C
    Temperature increases with height in the troposphere at an average rate of $6.5^{\circ} \mathrm{C}$ per kilometer.
  • Correct answer
    D
    Temperature decreases with height in the troposphere eat an average rate of $6.4^{\circ} \mathrm{C}$ per kilometre.

Solution

With increasing height, air temperature drops uniformly with altitude at a rate of approximately $6.4^{\circ} \mathrm{C}$ per Km in the troposphere.

Hence, the correct answer is option: 'D'.
