Weather fronts

Their are four different types of weather fronts that make up our weather. Their is a cold front, warm front, stationary front, and occluded front.

cold front= is when a front of cold air comes in over a warmed area and the heat then
rises above the cold air.

warm front= is when a front of warm air comes in and gets rid of the cold air and at the same time it is slowly rising.

stationary front= when a cold and warm air front both come in at opposite directions and they clide causing the cold air and warm are to split into 2 different sections.

occluded front= is when their are to cold fronts going on causing the warm air to rise.
