Review

Match the picture and definition to the correct weather term below.

Draggable itemCorresponding Item
The boundary between an advancing warm air mass and a receding cooler air mass
Air Mass
A body of air extending over a large area (1,000 miles or more) that develops and retains specific characteristics of pressure, temperature, and humidity
Atmosphere
Winds that act as a heat transfer system due to the unequal heating of Earth’s surface
Cold Front
A map or chart that shows the weather conditions at a specific point in time over a specific region
Forecast
Similar weather for a certain number of days
Global Winds
The border between an advancing cold air mass and a retreating warm air mass
Landforms
Directional movements of ocean water; surface currents result from steady winds over the ocean surface; deep currents result from density variations due to temperature and salinity differences
Ocean Currents
A prediction or estimate of future events
Warm Front
The day-to-day state of the atmosphere
Weather
Features on the surface of Earth, such as mountains, hills, dunes, oceans, or rivers
Weather Map
The layer of gas surrounding a planet that is held in place by gravity

Air Pressure and Weather

1

Let's review what we have learned about air pressure and how it relates to weather.

True or False-

Air pressure is the weight of the atmosphere pushing down on us.

1

What two factors influence air pressure?

1

Match the symbol with the correct pressure system.

Draggable itemCorresponding Item
Low-Pressure System
High-Pressure System
1

Match the characteristics below with the correct pressure system.

  • lighter air
  • heavier air
  • air rises
  • air sinks
  • air moves counterclockwise
  • air moves clockwise
  • clouds, breeze, and precipitation
  • clear and quiet weather
  • Low-Pressure System
  • High-Pressure System

Did you know?

1

Remember when we used our convection tubes to learn about air pressure...


We observed air move from areas of _______ pressure to areas of _______ pressure.

1

Atmospheric pressure comes from the weight of the air above us.

1

Pressure is highest at

1

Rising air leads to

1

Sinking air leads to

1

Air naturally wants to flow from

1

High pressure weather is often calm clear and sunny.

1

Low pressure weather is often cloudy and rainy.

Conclusion

What causes wind?
Create a diagram to explain. Be sure to use these terms in your response:

high pressure
low pressure
warm air
cool air
rising
sinking
