Final answer:
A warm front has a shallower slope than a cold front, resulting in a wide range of overcast skies and prolonged precipitation, with stratus and nimbostratus clouds. A cold front has a steeper slope with cumulonimbus or cumulus clouds, leading to shorter, but more intense, precipitation events.
Step-by-step explanation:
A warm front has a shallower slope compared to a cold front. When warm air moves over cold air, it does so gradually, resulting in a gentle incline, and thus a shallow slope. This produces a wide range of overcast skies and prolonged precipitation because the warm air lifts slowly over the colder air. Clouds commonly associated with warm fronts include stratus and nimbostratus clouds, leading to light to moderate rain or drizzle.
On the other hand, a cold front has a steeper slope as the colder and denser air pushes underneath the warmer air, which makes the warm air rise more rapidly. This often leads to a narrow band of heavier precipitation and a faster-moving weather front. Clouds that can be found in a cold front as it approaches include cumulonimbus or cumulus clouds, often associated with shorter, but more intense, precipitation events.
