What is Atmospheric Pressure?
Atmospheric pressure is the force exerted by the weight of air in the Earth’s atmosphere. It affects weather patterns, human health, and various industrial applications.
Causes of Atmospheric Pressure
It is primarily caused by gravity pulling air molecules toward the Earth’s surface, creating pressure that decreases with altitude.
Effects of Atmospheric Pressure
Changes in atmospheric pressure influence weather conditions, aviation operations, and even how our bodies function at different elevations.
Common Questions
How is atmospheric pressure measured?
It is commonly measured using a barometer, with units such as Pascals (Pa) or inches of mercury (inHg).
Why does atmospheric pressure vary?
Variations occur due to temperature changes, altitude, and weather systems like high or low-pressure areas.
