If temperature increases in a layer but pressure continues to decrease, which conclusion is correct?
Answer and explanation
Correct answer: Temperature and pressure do not always change in the same direction
The governing concept is the difference between vertical temperature variation and pressure variation. Pressure generally decreases with altitude because the overlying column of air becomes smaller, even in a layer where temperature increases with height, such as the stratosphere or thermosphere. Thus the two variables need not change in the same direction. Options B, C, and D incorrectly treat them as inseparable, so A is correct.
