1. Air Pressure!!!!!!!! By Ashlyn, Anna, and Layla.

2. Barometers The weight of the air is measured on the surface of the Earth with a barometer. This is a weather instrument.

3. Air Pressure Air pressure is the weight of the air around us. Air pressure refers to the weight of the atmospheric pressure.

4. The air inside your body presses out in the same force as the outside air presses in. Air pressure is the force produced by the weight of the air pressing down on the Earth.

5. Low pressure and warm air masses usually bring cloudy weather and a chance of storms.

6. High Pressure High Pressure usually brings good weather. High Pressure happens when the bits of things in the air are close together. The air is usually dry and cool. Without high pressure, we wouldn’t have good weather.

7. Do you wonder why you don’t feel air pressure??? Barometers measure air pressure. Since the pressure inside is equal to the outside pressure, you don’t feel a thing.

8. Weather and Air Pressure! Air Pressure is interesting! Weather is fun! It is good to learn about air pressure because if you can read a barometer, then you will know what the weather is. It helps you know about the weather outside. It is really interesting , because it’s the air that presses down to the Earth.
