The Nature of Weather: Air Pressure

The video tutorial explains the concept of air pressure, which is the force exerted by air on the Earth's surface. It discusses how air pressure is influenced by factors such as air density, temperature, and moisture content. Warmer air is less dense and exerts less pressure compared to cooler air. Similarly, moist air is less dense than dry air, resulting in lower pressure. Additionally, as elevation increases, air becomes thinner and less dense, affecting air pressure.

Discuss the relationship between moisture in the air and air pressure.

What happens to air pressure as elevation increases?
