Fronts

Cold Fronts:

Cold Fronts is when big fast moving cold air moves under the slow moving warm air. The reason why is cold air is more denser than warm air causing the cold air to sink. When the warm air rises than the air turns cooler causing water droplets from the cloud to drop. When there are cold fronts it changes weather so it could cause a hug thunderstorm and severe winds.

Warm Fronts:

Warm Fronts is when a slow moving warm air collides with a slow moving cold air. because the cold air i denser the warm air moves above the cold air. Clouds, Storms, and other precipitation is caused by warm fronts. If its a humid warm front then it would have light rain, Because the cold air is more denser than it could be more foggy or cloudy for a couple of days

Stationary Fronts:

In some cases the warm air and the cold air don't have enough force to go through each other. So they stay stationary. When the air meets it condenses the water vapor, and and the warm air into snow, rain or, fog. Sometimes it stays there for days.
