Air pressure, frequently referred to as atmospheric pressure, is the force exerted on a surface of an area caused by the Earth's gravitational attraction on the air vertically above that area. Air pressure varies with altitude and location. For instance, at the equator, where the tradewinds ...
What happens to the air pressure as the altitude increases? A. It increases. B. It stays the same. C. It decreases. D. It first increases then decreases. 相关知识点: 试题来源: 解析 C。解析:随着海拔高度增加,气压会降低。因为随着高度升高,上方空气柱的重量减小。A选项气压是降低而非增加,B...

Air pressure is greatest at Earth’s surface and decreases with altitude. This is why the air pressure is greatest at sea level but less in Denver, Colorado which has an altitude of 1.6 Km (1 mile).
Altitude is calculated from air pressure and vice versa. A detailed table and plot along with descriptions of the equations are included.
Altitude Air Pressure CalculatorAt sea level there is a pressure equivalent to 10 meters of water pressing down on all of us all the time. This is because of the weight of the air above us in the atmosphere. When you travel up a mountain, there is less air above you in the atmosphere...
