-The heights of the 500 mb surface in air column A is 5700 meters and 5640 meters in air column B.Choose the best answer from the following:

Question

Quizplus · Accepted Answer

The 500 mb surface is a pressure level where the atmospheric pressure is 500 millibars. The height of the 500 mb surface varies with temperature and pressure. In air column A, the height of the 500 mb surface is 5700 meters, which means the atmospheric pressure at that level is lower than in air column B, where the height is 5640 meters. This suggests that the temperature is higher in air column B, which is consistent with the fact that warm air expands and rises, leading to a lower pressure at that level. Therefore, the correct answer is E, both C (temperature in air column A is higher) and D (density in air column A is lower).
