How atmospheric pressure changes with altitude
Forces and motion • Pressure in fluids
Key concepts
What you'll likely be quizzed about
- Atmospheric pressure decreases as altitude increases due to the reduction in the weight of air overhead.
- At sea level, pressure is highest because the dense layer of air exerts more force.
- As one ascends mountains or flies in an airplane, the air becomes less dense, leading to lower pressure values.
