Question

Quizplus · Accepted Answer

Troughs are characterized by lower atmospheric pressures and are associated with cooler, sinking air. The height contours (lines of equal altitude) in the atmosphere for troughs are indeed shifted toward the equator compared to the surrounding air, indicating areas of lower pressure. This is because troughs represent elongated areas of low pressure in the atmosphere.
