What does pressure refer to in atmospheric terms?

Back

In atmospheric terms, pressure refers to the force exerted by the weight of the air above a surface.

How is density related to weather?

Back

Density in weather refers to the mass of air molecules in a given volume, affecting air pressure and weather patterns.

Front

What is the difference between climate and weather?

Back

Climate refers to the long-term patterns and averages of weather in a region, while weather describes the short-term atmospheric conditions.

Front

How does altitude affect air pressure?

Back

As altitude increases, air pressure decreases because there is less air above a surface exerting pressure.
