Why does temperature not decrease everywhere with height even though pressure decreases in atmospheric layers?
Answer and explanation
Correct answer: Because radiation absorption and energy processes differ across layers
Pressure generally falls with altitude because the overlying column of air becomes smaller, but temperature depends on how each layer gains and loses energy. In the stratosphere, ozone absorbs ultraviolet radiation and causes temperature to rise upward; in the thermosphere, absorption of high-energy solar radiation produces another warming trend. The troposphere is heated mainly from Earth’s surface and usually cools upward. Thus option A correctly separates pressure control from radiative heating; the other choices are scientifically false.
