Local Winds
Differences in air pressure and _____ cause air to flow.
temperature
The Earth has several large _______ cells that redistribute thermal energy around the world. (You can read these lines by going in 30 degree marks starting form the equator and going to the poles.)
convection
Hurricanes and tornados ______ because of the Coriolis Effect.
spin
Warm air takes up more space. It expands. Cool air takes up ______ space. Cool air contracts.
less
_____ is the movement of air from high pressure to low pressure?
Wind
Warm air ______ and cool air ______.
rises and sinks
The Coriolis Effect causes large masses of air and water in the Northern Hemisphere to bend to the _____, and large masses of air and water in the Southern Hemisphere to bend to the ______.
right and left
Heating and _______ of the Earth make wind.
cooling
The sun warms the land quicker and the temperature above water is cooler. When these two pressures mix it creates ________?
sea breeze
the _______ _______ are steady winds that flow from east to west between the equator and 30 degrees N to 30 degrees south.
trade winds
false. The equator is 25,000 miles long and the poles only 6ft.
A ________ is what scientists use to measure pressure in the atmosphere.
barometer
At night, when land cools off the air above it is cooler and the air above water is warmer. When these two pressures mix together it creates a ________.
land breeze
These are cold winds that blow from east to west near the North and South Poles.
Polar Easterlies
Global winds and ocean currents bend because of the Coriolis Effect? True or False.
True
When we have high barometric pressure the weather is normally ______ and when we have low barometric pressure its _______.
Sunny and stormy
Can a sea breeze occur at night?
yes, only if the land stayed warmer than the water.
The _______ _______ are winds that flow form 30 degrees N and 30 degrees S to 60 degrees N and 60 degrees south. They flow from west to east.
Prevailing Westerlies
How does the Coriolis Effect impact hurricanes?
The Coriolis Effect makes hurricanes spin. In the Northern Hemisphere, they spin clockwise and in the Southern Hemisphere they spin counterclockwise.
Wind erodes mountains and other pieces of land. Erode is from an old word that means "wear away." Wind is always _____ Earth's landscape.
