What is Atmospheric Pressure?

Atmospheric pressure is the force exerted by the weight of air in Earth’s atmosphere. Measured in units like Pascals or atmospheres, it affects weather, altitude, and daily life. Understanding this concept is key to fields like meteorology and aviation.

Causes of Atmospheric Pressure

Gravity pulls air molecules toward Earth, creating pressure. Variations occur due to temperature, altitude, and weather patterns. For a deeper dive, define atmospheric pressure with expert resources.

Effects on Weather and Health

Changes in pressure influence storms, winds, and even human health, causing issues like altitude sickness. Monitoring helps in forecasting and safety.

FAQ Section

How is atmospheric pressure measured?
It’s commonly measured with barometers, in units such as hPa or mmHg.

Why does pressure decrease with altitude?
Air density reduces at higher elevations, lowering pressure.
