Which type of front spreads clouds and rain over a large geographical area?

A warm front is characterized by a mass of warm, moist air that slides over a cold air mass. As the warm air rises, it cools and condenses, forming clouds and precipitation. This process often results in widespread cloud coverage and rain over a broad geographical area, creating a gradual transition in temperature and weather conditions.

Warm fronts typically bring steady, continuous rainfall that can last for an extended period, leading to more uniform weather patterns compared to cold fronts, which are known for sharper changes and more intense but shorter-lived storms. The gentle slope of warm fronts allows them to cover larger areas with clouds and rain, affecting a wide region, rather than just a narrow band.

Other options such as cold fronts often lead to more localized, intense thunderstorms, while stationary fronts can cause extended periods of rain in specific areas but do not necessarily spread clouds and rain over large regions like warm fronts do. Occluded fronts are also complex and can vary in the type and extent of precipitation they produce depending on the characteristics of the air masses involved.
