What is Atmospheric Pressure?
Atmospheric pressure, often referred to as air 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 industrial applications.
Key Causes of Atmospheric Pressure
The primary cause is gravity pulling air molecules toward the Earth, creating pressure. Temperature and altitude variations also significantly influence pressure levels, with higher altitudes resulting in lower pressure.
Effects on Weather and Health
Changes in atmospheric pressure drive weather systems, leading to storms or clear skies. For humans, rapid pressure shifts can cause discomfort, such as ear popping or headaches, especially during air travel or at high elevations.
Frequently Asked Questions
How is atmospheric pressure measured?
It is commonly measured using a barometer, with units like hectopascals (hPa) or inches of mercury (inHg).
Why does pressure decrease with altitude?
As altitude increases, air density and the weight of air above diminish, reducing pressure.
