All the air molecules in the atmosphere exert a force, or pressure, on our bodies.
Atmospheric pressure is the force exerted by the weight of the air above an object or surface.
Variations in pressure generate winds, which play a significant role in day to day weather conditions. The purpose of this activity is to introduce characteristics of pressure, high and low pressure centers, and a brief analysis of an idealized pressure field. Key words throughout this activity link directly to helper resources that provide useful information for answering the questions. Please explain why pressure changes this way with height. Do the same for a low pressure center .
