Atmospheric Pressure
Atmospheric Pressure
ATMOSPHERIC PRESSURE: We live at the bottom of an ocean of air. The atmosphere, much like the water in a lake, exerts a pressure.
Just as water pressure is caused by the weight of water, atmospheric pressure is caused by the weight of air. We have adapted so completely to the invisible air that we sometimes forget it has weight. Perhaps a fish forgets about of water in the same way. The reason we dont feel this weight crushing against our bodies is that the pressure (blood pressure) inside our bodies equals that of the surrounding air.There is no net force for us to sense.
The pressure of the atmosphere is not uniform. Atmospheric pressure is measured by barometer. Measurement of changing air pressure is important to meterologists in predicting weather.
Atmospheric pressure is maximum at the surface of the earth and decreases as we move upwards. The value of the atmospheric pressure at sea level is
