Compared with warm fronts, cold fronts are a: faster moving b: less dense c: more cloudy or d: less steep

A: faster moving

Explanation:

The cold fronts are air masses that are cold. They tend to be dense, cold, and dry. These fronts are also much steeper than the warm fronts. The cold fronts are much more powerful than the warm fronts, which is mostly because of their higher density. They managed to move much quicker, to push the other air masses out of its way, and to pass much longer distances than any other type of front. As the cold fronts are moving quickly, they are able to cause drop in the temperature of up to 15 C degrees in only one hour.
