Weather Things: Air

Air is composed mainly of nitrogen and oxygen, with water vapor varying significantly. It plays a crucial role in supporting life and maintaining Earth's temperature. Air movement, driven by the sun, affects weather patterns through high and low-pressure systems. Aerosols in the air can travel globally, affecting sky color and weather. Air is essential for flight, sound, and life. Wind results from air pressure differences, with rising warm air creating low pressure and sinking air creating high pressure, forming a continuous cycle.
