What is Atmospheric Pressure?
Atmospheric pressure, also known as air pressure, is the force exerted by the weight of air molecules in Earth’s atmosphere. It plays a critical role in weather patterns, human health, and various industrial applications.
Causes of Atmospheric Pressure
Gravity pulls air molecules toward Earth, creating pressure. The density and temperature of air also influence pressure levels, causing variations across different altitudes and regions.
Effects of Atmospheric Pressure
Changes in atmospheric pressure affect weather conditions, leading to storms or clear skies. It also impacts aviation, scuba diving, and even human blood pressure.
Common Questions
How is atmospheric pressure measured?
It is measured using a barometer, typically in units like Pascals (Pa) or inches of mercury (inHg).
Why does pressure decrease with altitude?
As altitude increases, air becomes thinner, resulting in lower pressure.
