Seventh Grade Week 27

This week's topic is the weather.

What causes High and Low pressure in the atmosphere?
What makes the winds blow?

Hopefully our contracts will take us outside to see the weather.

  1. A "High" is when the air pressure is higher than the air around it.
    A "Low" is when the air is lower than the ari surrounding it. Mr. Hoopman you use an Aneroid Barometer right?

  6. The wind blows because the high pressure and low preasure cause the air to move because of the different temperature.

    Hot air makes low pressure because it rises, and cold air makes high pressure because it sinks.

  17. *Air pressure is caused by movement of molecules on each other, and elevation & density affect it too. *LOW is at higher elevations because less air is pushing down on it & has less dense air.
    *HIGH is at low elevation and higher dense air because more air is pushing down on it
