indian-world-geographyclimatology
- AStratosphere
- BMesosphere
- CThermosphere
- DTroposphere
Explanation
Temperature falls with height through the troposphere, rises through the stratosphere (ozone heating), then falls again through the mesosphere, reaching the atmosphere's coldest point (around −90°C) at the mesopause. The thermosphere above is extremely hot, though tenuous. Hence the lowest temperatures are observed in the mesosphere.
