In what ways do cold fronts form differently from stationary fronts?

• Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances against a warm air mass.

• Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is trapped between two cold air masses.

• Cold fronts form when a warm air mass moves over a cold air mass, while stationary air fronts form when a cold air mass moves over a warm air mass.

• Stationary fronts form when a warm air mass is trapped between two cold air masses, while cold fronts form when a warm air mass moves over a cold air mass.

An occluded front is different from a cold front in what way?

• Warm air is pushed up during an occluded front, while cold air moves quickly during a cold front.

• Occluded fronts cause warm air to feel dry, while cold fronts cause ground temperatures to feel cooler.

• Warm air moves slowly during an occluded front, while cold air is cut off from the ground in a cold front.

• Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation.

What causes air masses to move?

• A difference in air pressure and temperature occurs.

• Weather conditions change rapidly to produce storms.

• A collision takes place between two natural wind patterns.

• Long, narrow bands of wind blow in the upper atmosphere.
