What is the main reason temperature decreases with height in the troposphere?
Answer and explanation
Correct answer: Heating from Earth’s surface below
The troposphere is heated indirectly: Earth’s land and oceans absorb solar energy and then warm the air in contact with the surface. As altitude increases, air pressure falls and rising air expands and cools, producing the normal lapse rate. Therefore option A is correct. Increasing direct solar heating would not explain the usual decrease, while ozone and ionised particles are characteristic of higher atmospheric regions rather than the main cause here.
