There is a layer of air surrounding us. Atmospheric pressure is the result of a huge layer of air pushing against the surface of the earth. The pressure of the atmosphere is greater on the surface of the ocean. As we move higher from the surface of the earth, the atmospheric pressure decreases. Low pressure occurs when gases become hot and move upward in a region with high temperatures. Humidity and cloudy weather are associated with low pressure. Low-temperature regions have a cool atmosphere, which increases the pressure.
