Cold fronts

Question

Cold fronts

Quizplus · Accepted Answer

Cold fronts are boundaries where cold air masses come into contact with warm air masses, causing the warm air to rise and cool down, leading to the formation of clouds and possibly precipitation. This process creates a converging zone, where the colder air displaces the warmer air, leading to changes in atmospheric pressure, wind direction, and temperature. Thus, choice D, which states that cold fronts cause convergence when they meet warm air, is the correct answer. Choices A and C are incorrect because cold fronts are associated with cooler and often more severe weather conditions, and they have a distinct forward edge. Choice B is incorrect because the upper boundary of a cold front typically slopes backward, not forward.
