What is Atmospheric Pressure?
Atmospheric pressure is the force exerted by the weight of air in the Earth’s atmosphere. It plays a crucial role in weather patterns, human health, and various scientific applications.
Causes of Atmospheric Pressure
This pressure results from air molecules colliding with surfaces. Gravity pulls these molecules downward, creating pressure that decreases with altitude.
Measuring Atmospheric Pressure
Barometers are used to measure atmospheric pressure, typically in units like Pascals or inches of mercury. Accurate measurement is vital for meteorological forecasts.
Effects on Weather and Health
Changes in atmospheric pressure influence weather systems, often indicating storms or clear skies. It also affects human physiology, particularly at high altitudes.
FAQs
How does atmospheric pressure impact daily life?
It affects weather predictions, aviation, and even how we breathe in different altitudes.
Why does pressure decrease with height?
There are fewer air molecules at higher elevations, reducing the force they exert.
