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

• the Coriolis Effect

• 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
