Wind
Which interaction causes the Polar Easterlies to flow from the North and South Poles?
Cold, dense air from the poles replaces rising warm air. Convection
describes the changes in the air as it moves from ocean to land
The sun heats the land faster than the ocean water, so high-density air moves from the ocean to the land, becoming less dense.
The Gulf Stream moves from the tropical latitudes up the eastern coast of the United States. After crossing the Atlantic Ocean it moves towards Britain in northwestern Europe. This results in Britain having a much warmer climate than the surrounding countries.
What is the source for the contrasting climate?
Radiant energy from the Sun and the Coriolis Effect causes ocean currents to move in specific directions.
