• Differences in air pressure on Earth’s surface cause wind.
• Warmer air is less dense than cooler air.
• Air flows from areas of higher pressure to areas of lower pressure.
• Earth’s rotation causes winds to curve to the right in the Northern
Hemisphere and to the left in the Southern Hemisphere.
• Sir Francis Beaufort created a scale to measure wind speed.
