Question #3: How many kinds of fronts are there?
There are six types of weather fronts. The first two are the most known and common-the warm&cold fronts. An occluded front is when the cold front takes over the warm one. Stationary fronts are the boundaries of two air masses that cannot overcome one of the other and the front tends to just stay in place. Dry lines are air masses with different moisture levels, which means that one has warmer, less dense air than the dry air mass. Squall lines are cold fronts that have split into two, usually during the summer season, and can cause dangerous weather such as tornadoes.

Cold and warm fronts are the most common. When cold air pushes warm air up, it is called a cold front. Cold fronts normally bring thunderstorms. When the warm air pushes the cold air down, it's called a cold front. Normally after a warm front, there is a fog.
