Question

Q. Consider the following types of Lapse rates:

Arrange the above given rates in ascending order of their lapse rate:

• A.
  1-2-3
• B.
  3-1-2
• C.
  1-3-2
• D.
  2-3-1

Answer 1

The correct option is B

3-1-2

Explanation: The lapse rate is the rate at which an atmospheric variable, normally temperature in Earth's atmosphere, falls with altitude. It varies depending upon the amount of moisture present in the atmosphere. The dry air experiences the most rapid fall in temperature while in case of an excessively moist air it is the least. The different rates are :

3. Wet Lapse rate: 5℃/km.

1. Normal lapse rate: 6.5℃/km.

2. Dry lapse rate: 10℃/km.
