Air and Wind Currents Flashcards
Does warm or cold air rise
warm
does warm or cold air sink
cold
where does air warm
the ground
where does air cool
high up
make a “square circle”
convection currents
Air in the earth tire
High Preassure
Air out/away from the earth “tire”
low pressure
Northern Winds turn
clockwise (9 to 12, 3 to 6)
southern winds turn
counter-clockwise (9 to 6, 3 to 12)
what fuels currents
heat from the sun
Energy traveling through space
Radiation
How does heat get from the sun to the earth
radiation
Heat transferred from one object to another or one molecule to another
conduction
Heat is absorbed by the land by
conduction
heat is distributed over eath by
convection
The transfer of heat through fluids
convection
At the equator, the sun’s radiation hits nearly directly at almost
90 degrees
concentrated at smaller surface area
solar radiation
since Solar radiation is concentrated at smaller surface area, this means there will be
warmer temperatures
At poles, the sun’s radiation hits at more of an
angle
Spreads the radiation over a larger area =
cooler tempertures
Warm air is ____ dense than cold air.
less
Something with higher density _____.
sinks
Earth is neither _____ nor _______
still/smooth
sinks and flows away from the poles.
cold air
cold air Collides with air from equator around _____ latitude and gets pushed up
60 degrees
Air can either move back to _____ (to repeat process) or towards the ______
poles/equator
