Options
- Aupper part of ionosphere.
- Bupper boundary of the tropopause.
- Clower part of mesosphere.
- Dupper boundary of stratopause.
Correct answer
D. upper boundary of stratopause.
Step-by-step solution
The lapse rate is the rate at which an atmospheric variable, normally temperature in Earth's atmosphere, changes with altitude. Lapse rate arises from the word lapse, in the sense of a gradual change. It corresponds to the vertical component of the spatial gradient of temperature.
