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, aviation, and even human health. Understanding this concept helps explain many natural phenomena.

Causes of Atmospheric Pressure

Gravity pulls air molecules toward the Earth, creating pressure. This pressure varies with altitude and temperature—higher elevations have lower pressure, while denser air at sea level results in higher readings.

Effects on Weather and Health

Changes in atmospheric pressure influence weather systems, often indicating storms or clear skies. It also affects bodily functions; for instance, low pressure at high altitudes can cause shortness of breath.

Common Questions Answered

How is atmospheric pressure measured?
It is typically measured using a barometer, with units like Pascals (Pa) or inches of mercury (inHg).

Why does pressure decrease with altitude?
As altitude increases, air density and molecular weight decrease, reducing pressure.
