Which of the following statements about frontal movements is true?

The correct statement is that a cold front generally passes faster than a warm front. This phenomenon occurs due to the differences in density and temperature between the two air masses. Cold air is heavier and denser compared to warm air, enabling cold fronts to push through an area more quickly. As a result, when a cold front advances, it often leads to more abrupt weather changes, such as rapid temperature drops and increased precipitation, compared to the more gradual changes associated with a warm front.

In contrast, warm fronts tend to move more slowly because they are advancing warm, lighter air over cooler, denser air. This gradual lifting of the warm air leads to a slower rate of movement and often results in a more prolonged period of cloudy weather with steady precipitation as the warm air gradually rises and cools.

The idea that both fronts move at the same speed does not account for the physical properties of the air masses involved, while a stationary front’s lack of movement is not applicable since it neither advances nor retreats, making it inherently slower than either type of moving front.
