What is air pressure? It is the weight of air molecules pressing down on the Earth. The pressure changes as you move upward into the atmosphere. The greatest density of air is at sea level.

Jared shows us the power of air pressure using the egg and bottle demonstration. This video was previously called "What is Air Pressure".Visit our channel fo...

Discover what air pressure is, how it's measured, and why it's important for weather forecasting. Learn about high and low pressure and how they shape the skies.

What is Atmospheric Pressure? Air might seem light, but it actually has weight. Imagine a tall column of air stretching from the sky all the way down to the ground. The weight of all that air in the column …

One important type of pressure is the pressure exerted on objects from the air or the Earth's atmosphere. This is actually the measurement of the weight of the gas above an object on a given …

Air pressure is the weight of air pressing down on Earth's surface and everything on it. Even though we can't see air, it's made of tiny molecules that have weight.

Atmospheric pressure, also known as air pressure or barometric pressure, is the pressure within the atmosphere of Earth caused by the weight of the air above us.

The atmosphere that surrounds Earth has weight and pushes down on anything below it. The weight of air above a given area on Earth’s surface is called atmospheric pressure.…

Air molecules get hyper too and love to bounce around! This excitement, coupled with the force of gravity, causes air molecules to have weight and put pressure on everything they touch. This is...

Air pressure is the force of air pushing down on us from the atmosphere. Even though we don’t feel it, air is always pressing on us from all directions! Why does air have pressure? The Earth’s atmosphere is …
