1. Air pressure, also called atmospheric pressure, is the force exerted by the weight of air in the atmosphere. It varies based on elevation, with higher pressure at sea level (1013.25 millibars) and decreasing with increase in elevation. 2. Several factors influence air pressure, including temperature, elevation, and moisture content. Areas with high temperatures generally experience high pressure, while low temperatures result in low pressure. Air pressure also decreases with increasing elevation as the weight of air above decreases. 3. The distribution of land and oceans also affects air pressure. Areas near the equator over land experience low pressure since rising air is more heated, while areas over oceans near the equator experience high pressure
