As atmospheric pressure steadily becomes lower at increasing heights above sea level, less heat is needed to boil water.

Low or Low Pressure Area - an area of low pressure usually characterized by clouds of precipitation caused by rising air; often related to inclement weather such as winds flowing counter clockwise and into the center of the low.

Did you realise that your geographical location affects a very important component of cooking: the way water boils?

Thanks to gravity, the atmosphere has weight. In fact, about a ton of air is pressing down on you constantly, but you don’t feel it because the same air pressure surrounds and supports you. Air pressure is measured with a barometer. When air is cold and dry, it weighs more, or has high pressure. So the barometer is higher in fair weather. When air is wet, it weighs less, or has low pressure. So the barometer is lower when it is raining. Changing barometric readings indicate a change in…

Pressure, in the physical sciences, perpendicular force per unit area, or the stress at a point within a confined fluid.

In this activity, students indirectly measure atmospheric pressure using a plastic drink bottle and a ping pong ball. They will then use this measure to calculate the force acting on the outside of a...

Anticyclone - a body of air in which the atmospheric pressure is higher than the pressure in the surrounding air; a high or high pressure area. An anticyclone creates clear, dry weather.

Atmospheric pressure is the force exerted against a surface by the weight of the air above the surface.

Atmospheric pressure and layers

Students investigate the weather from a systems approach, learning how individual parts of a system work together to create a final product. They learn how a barometer works to measure the Earth's air pressure by building a model using simple materials. Students analyze the changes in barometer measurements over time and compare those to actual weather conditions. They learn how to use a barometer to understand air pressure and predict real-world weather changes.

Pressure can be thought of as the weight of the air above the Earth’s surface. The force exerted by an air mass depends on its molecules — how many there are, their size and motion.
