**What is Atmospheric Pressure?**
Atmospheric pressure is the force exerted by the weight of air in the Earth’s atmosphere. Measured in units like pascals or millibars, it impacts weather patterns, human health, and scientific applications. Understanding the atmospheric pressure definition is key to grasping how air influences our daily lives.
**How It Works and Measurement**
Atmospheric pressure decreases with altitude due to less air above. Instruments like barometers measure it, aiding in weather forecasting and aviation safety. Variations cause wind and storms, making it vital for environmental studies.
**Common FAQs**
Why does pressure change with weather? Low pressure often brings rain, while high pressure indicates clear skies. These shifts drive meteorological events.
How does it affect humans? Changes can cause ear discomfort or altitude sickness, emphasizing the need for adaptation in travel and sports.
**Applications and Importance**
From predicting storms to designing aircraft, atmospheric pressure is crucial. Industries rely on accurate measurements for safety and efficiency.
