Atmospheric Pressure and Altitude | GCSE Physics
The atmosphere is a thin layer of air round the Earth. It gets less dense as altitude increases.
Why is it harder to breathe at the top of a high mountain?
What is Atmospheric Pressure and Altitude | GCSE Physics?
"The pressure within the atmosphere of the Earth."
As you move higher up into the atmosphere, the density of the air ____.
Atmospheric pressure is caused by air molecules ____.
Why does a crisp packet puff up when taken on an airplane flight?
Atmospheric Trends
Atmospheric pressure is created by air molecules colliding with a surface.
Number of air molecules above a surface decreases as altitude increases.
Pressure decreases as you go higher up in the atmosphere.
The atmosphere is much thinner compared to the Earth's radius.
Graph Tip: The relationship between altitude and pressure is not linear; pressure drops faster at lower altitudes.
