What is Atmospheric Pressure?
Atmospheric pressure is the force exerted by the weight of air molecules in Earth’s atmosphere. It plays a crucial role in weather patterns, aviation, and even human health.
Definition and Basics
To define atmospheric pressure, it’s the pressure within Earth’s atmosphere, commonly measured in units like Pascals or millibars. It decreases with altitude due to fewer air molecules above.
Key Causes
Gravity pulls air molecules downward, creating pressure. Temperature and humidity variations also influence it, leading to changes in weather systems.
Effects on Environment
Atmospheric pressure drives wind formation and storm development. Low pressure often brings rain, while high pressure results in clear skies.
FAQs
How is atmospheric pressure measured?
It’s typically measured with a barometer, providing data for weather forecasting.
Why does pressure change with weather?
Temperature shifts cause air density variations, altering pressure and influencing climate conditions.
