Answer:
<em>3 types of front: cold front (cool air and cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies) , warm front ( warm air and high clouds like cirrus), and stationary front(warm and cool air and stratus, nimbostratus, altostratus, and cirrostratus clouds. </em>
Explanation:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.
Stationary front Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or “standing still.” Where the warm and cold air meet, clouds and fog form, and it may rain or snow.
