Question

4. Lapse rate in troposphere is-
(A) Negative
(B) Positive

(D) Both of the above


​

Answer 1

Answer:

This coldest layer of the atmosphere, where the lapse rate changes from positive (in the troposphere) to negative (in the stratosphere), is defined as the tropopause. Thus, the tropopause is an inversion layer, and there is little mixing between the two layers of the atmosphere.
