How does the Gulf Stream current affect climate?
It circulates cold water around the Gulf of Mexico
It moves cold water from the equator toward the poles
It moves warm water north along the eastern coast of the US and on toward Britain
It brings upwelling to California
What factor most influences the movement of deep ocean currents?
differences in density

continental deflection
global winds
Atmospheric greenhouse gases heat the atmosphere by
increasing the amount of solar radiation coming from the sun
storing up energy produced by human activity
increasing the average density of air
trapping heat energy that would otherwise get re-radiated back into space
What instrument measures air pressure?
thermometer
anemometer
barometer
wind vane
High pressure means __________.
clear skies
rainy or cloudy
What is wind?
movement of air due to pressure differences
disturbances in the magnetic field
movement due to Earth's rotation
the formation of clouds in the lower atmosphere
How do differences in air pressure affect the movement of air?
Air always moves from east to west.
Air always moves from areas of low altitudes to high altitudes.
Air always moves from areas of low pressure to areas of high pressure.
Air always moves from areas of high pressure to areas of low pressure.
