In which lower layer does temperature first decrease before increasing above it in the stratosphere?
Answer and explanation
Correct answer: Troposphere
The governing vertical temperature pattern is a decrease with height in the troposphere followed by an increase through the stratosphere. The troposphere is heated from Earth’s surface, so rising air generally becomes cooler; ozone absorption then warms the stratosphere upward. Therefore option B is correct. The exosphere and thermosphere are much higher, and the mesosphere lies above the stratosphere rather than below it.
