What type of front has a steep slope and is associated with good visibility and cumulus clouds?

The type of front characterized by a steep slope, good visibility, and the presence of cumulus clouds is indeed a cold front. Cold fronts occur when a colder air mass moves into an area occupied by warmer air, forcing the warm air to rise rapidly. This rapid upward movement of air leads to the formation of cumulus clouds, which can develop into cumulonimbus clouds, often associated with showers and thunderstorms.

Additionally, cold fronts are typically marked by a sudden drop in temperature and a shift in wind direction. As the cold air pushes underneath the warm air, it can create a clearer atmosphere behind the front, resulting in improved visibility. The steep slope of cold fronts contributes to the development of these cloud types, distinguishing them from warm fronts, which have a more gradual slope and are generally associated with overcast skies and continuous precipitation.
