In describing weather completely, it is important to include, among other aspects, air pressure, precipitation, and humidity. Which of the following statements is false? Wind is the movement of air that results from differences in air pressure.

Precipitation is a form of water that falls to Earth’s surface from the clouds.

Air typically moves from areas of lower pressure to areas of higher pressure.

When the temperature of the air cools to the dew point, the air is saturated, and water droplets will form.
