Attic Ventilation 101

Attic ventilation relies on the principle that hot air rises and cold air falls. Soffit vents allow air intake into the attic space, and ridge, gable, and roof vents allow the hot air to escape. This creates a circular flow which helps prevent hot moist air from causing mold and rot. Proper ventilation also help reduce heating and cooling costs. There is an excellent video in the link below explaining the basic principles in attic venting.
