Air Pressure & Wind

When warm air rises and cools high in the atmosphere and then sinks to the earth creates _________ currents

• convection
• surface
• deep
• precipitaiton

Instruments used to measure air pressure are called

• thermometers
• hygrometers
• hydrometers
• barometers

Winds are caused by differences in

• precipitation
• humidity
• air pressure
• turbulence

Warm air rising at the equator and cold air sinking at the poles is one reason for which event?

• hurricanes
• Coriolis Effect
• Earth's rotation
• convection currents

How far above sea level is called what?

• temperature
• altitude
• greenhouse effect

Global winds generally

• are unpredictable
• change directions day to day
• blow from specific directions over long distances

What causes winds?

• differences in precipitation
• differences in humidity
• differences in air pressure

What causes global winds to curve?

• coriolis effect
• albedo
• doldrums

The _______________________________ is responsible for the weather, rain, or snow

• Exosphere
• Thermosphere
• Magnetosphere

Low pressure systems are characterized by

• counterclockwise air flow and cloudy rainy weather
• sunny weather
• clockwise air movement
• calm, clear days
