Wind

Global wind Systems are

• Polar Easterlies, Westerlies and Trade Winds

• Effect  acceleration of a moving body on or near the Earth as a result of the Earth's

• As temperature decreases, pressure increases.

• The Polar Easterlies blow on water in the poles.

The air around the equator has a high temperature , so it has a

• medium air pressure

• high air pressure

• low air pressure

• no air pressure

Why does Earth have a large convection current

• temperature difference between North and South pole

• Direction of trade winds

• temperature difference between the equator and the poles

• the water cycle

What causes uneven heating on Earth?

• Earth's revolution

• Temperature differences

• Global Trade Winds

• Earth's rotation

The polar Easterlies blow on water. The air of this type of wind most likely has a 

• low pressure

• High pressure

• medium pressure

• no pressure

As temperature decreases, pressure 

• Increases

• decreases

• stays the same

• goes up and down

How do Horse latitudes and Doldrums act as a convection current?

• cool air rises in Doldrums while warm air falls in Horse latitude

• warm air rises in Horse latitudes, while cool air falls in Doldrums

• Warm air rises in Doldrums, while cool air falls in Horse latitudes

• Cool air rises in Horse Latitudes while warm air falls in Horse latitudes

What should a pilot know while flying his plane?

• Trade Winds and Coriolis Effect

• Trade winds only

• Coriolis effect only

• Prevailing Westerly Winds

Prevailing Westerlies are found..

• 90 degrees north of the equator

• equator

• between 60 and 90 degrees west and east longitude

• between 30 and 60 degrees north and south latitude

Earth has a large convection current because

• a high temperature, so it has a low air pressure

• high pressure air

• temperature difference between the equator and the poles
