where does wind from
high and low pressure areas
When there is a difference in air pressure what is created
wind
the movement of air parallel to Earth’s surface is
wind
why does the Earth’s atmosphere have high and low pressure areas
uneven heating of the earths atmosphere
what kind of pressure is warm air
low pressure
what kind of pressure is cool air
high pressure
what does and anemometer measure
wind
what are blows over short distances and affects local weather
Local winds
what are 2 types of local winds and where do they come from
sea and land breezes
what are patters of wind that move around the globe
global winds
the sun hits the _______ most directly and less directly at the polles
equater
when the sun hits the equater is causes a huge difference in _________
Temperature
The air at the equater is less dense so it ( rises/ sinks)
rises
Then, once the air rising from the equator gets high enough it starts to (cool/ warm) which causes it to ( rise/ sink)
cool, sink
As It does, it will move toward the ( Equator/ poles) to take its place
equator
_______ _________ is when the Earth, rotates winds and water rotates
Coriolis Effect
which direction do the winds turn in the Northen hemisphere
clockwise
which direction do the winds turn in the southern hemisphere
counter cockwise
What are calm areas were air rises or sinks called
Doldrums and horse Latitudes
what are major global wind belts
tradewinds, Polar Easterlies and Prevailing Westerlies
Wind Belts are not _________ but and can travel around from month to month
stationary
What is the most important this tat that global winds do
push global winds from the equator to the poles
why is distributing the heat from the sun so important
so we can keep living
