Calculating Pressure | Pressure = force over area |
Atmospheric pressure is exerted on everything on | Earth |
Most of Earth's atmospheric pressure is | closer to Earth |
If you travel to higher or lower points in the atmosphere . . . | fluids in your body have to adjust to maintain equal pressure |
What is a fluid that exerts pressure like the atmosphere does | Water |
When a diver goes deeper into the water | atmospheric pressure and water pressure are part of the pressure on the diver |
Water is | about 1,000 times more dense than air |
When you drink through a straw | you remove some of the air in the straw - less air lowers the pressure |
Inhaling | decreases pressure in lungs |
Tornado | Air pressure inside is lower than air pressure outside |
