Quizplus · Accepted Answer

A ridge aloft is associated with warm air, as warm air rises and creates a dome-shaped ridge in the upper level of the atmosphere. Conversely, a trough aloft is associated with colder air, as cooler, denser air sinks and creates a trough-shaped dip in the upper level of the atmosphere. Therefore, the best choice is B, which correctly matches a ridge with warm air and a trough with cold air.
