What is the main reason temperature feels lower in mountain regions within the troposphere?
Answer and explanation
Correct answer: Temperature generally decreases with height
The governing concept is the normal lapse rate in the troposphere. Air is heated mainly by Earth’s surface; as altitude increases, pressure falls and rising air expands and cools. Consequently, temperature generally decreases with height, making mountain regions colder than nearby lowlands. Therefore option A is correct. Ozone, the exosphere and meteors do not explain ordinary temperature differences between mountains and plains.
