6-8 How do winds form?
SWBAT: Explain how winds form.
wind: horizontal movement of air
air current: up-and-down movement of air
• Winds are caused by differences in air pressure. Winds blow from regions of higher air pressure to regions of lower air pressure.
• Wind is air that moves horizontally along Earth’s surface.
• Air currents are caused by unequal heating of air.
