Air Pressure and the Wind

Air Pressure & Wind

What role does air pressure play in weather conditions?

• Its force determines the strength of wind.

• It primary trades are winds.

• You have to check your tire air pressure at Tucker's store.

Air Pressure & Wind

What gives wind its mass?

• barometric pressure

• air molecules

• air pressure

• Sully and Wesley flying kites in the wind.

Air Pressure & Wind

Which three elements affect air pressure?

• height above sea level, temperature, and amount of water vapor

  
  

• temperature, wind, and how much plant or animal life is around

• How fierce Sam plays soccer at a tournament.

• ocean , wind, and the amount of rain

Air Pressure & Wind

What is a convection cell?

• extremely dense and heavy masses of air

  
  

• a place on the beach where scientists watch weather

• an instrument scientists use to measure wind speeds

• a pattern of rising warm air and sinking cold air

Air Pressure & Wind

Why does air rise over land at the beach?

• Cold air gets warmer over land, which makes it lighter, so it rises.

• Warm air over the sea moves inland, gets cooler, and then rises.

• Trade winds around the Equator blow the air higher at the beach.

• When the girls, Claire, Emma, and Khloe road in the hot balloon on Field Day, the air was very warm on land.

Air Pressure & Wind

Which best describes the Coriolis Effect?

As it spins on its axis, the Earth pulls the wind and causes it to blow in a curved path.

• As cool air warms up, it rises, and as warm air cools down, it sinks, creating a breeze.

• As the Sun rises and sets, the path of the wind all over Earth changes directions.

• Trevor and Ellic flew in a Supersonic jet and the earth's wind were blowing in a curvy motion.

• As it spins on its axis, the Earth pulls the wind and causes it to blow in a curved path.

Which kind of wind blows across most of the United States?

Polar Windbacks

• Trade Winds

• Polar Easterlies

• The wind that blows Charlie's kite .

• Prevailing Westerlies

Is climate long-term or short-term?

• Long- term

• short-term

Is weather short-term or long-term?

• Long-term

• Short-term

What measures air?

• Putting a string in the wind to measure its pressure.

• A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure.

• The wind machine measures air pressure

• Walter has this machine on his land, the air thermometer that tells him the air pressure.
