What causes differences in air pressure?
even heating of the Earth
even cooling of the Earth
unequal heating of the Earth
increased heating of the EArth
The movement of the air caused by differences in air pressure is called
dense air
wind
polar air
vents
Air is warmer and less dense than surrounding air at the equator because the equator receives more
wind
air pressure
solar energy
radiation
Because air at the poles is colder and denser than surrounding air, it
rises
sinks
circulates
stagnates
After high pressure areas are created around the poles, cold polar air flows toward
the equator
the north pole
the south pole
the atmosphere
Which of the following are local winds?
mountain breezes
convection cells
polar winds
westerlies
What causes wind?
differences in air pressure
differences in gravity
differences in oxygen
differences in the thermosphere
What causes differences in air pressure around the Earth?
warm air rises at the equator, and cold air sinks at the poles
warm air sinks at the equator, and cold air rises at the poles
warm air rises at eh equator and cold air rises at the poles
cold air rises at the equator, and warm air sinks at the poles
Air moves in large, circular patterns called
pressure belts
convection currents
convection cells
trade winds
Why does warm air rise and cold air sink?
because warm air is less dense than cold air
because warm air is denser than cold air
because cold air is less dense than warm air
because warm air has less pressure than cold air does
Narrow belts of winds that can reach 400 km/hr are called
jet currents
jet streams
convection currents
convection streams
Local winds are produced
by global winds
global geographic features
local farms and ranches
local geographic features
Mountain and valley breezes are caused by
differences in temperatures and elevation
similarities in temperature and elevation
the same temperature at all elevations
high temperatures at all elevations
When the paths of winds and ocean currents seem to curve because of the Earth's rotation it's called
Earth's spin
Coriolis Effect
Earth's rotation
As the World Turns
