True or False. The Gulf Stream is one of the Earth's strongest currents. It moves north from the tropics through the Gulf of Mexico, past the east coast of the U.S. and up to northern Europe. As a result of the Gulf Stream, Europe is colder than Canada at the same latitude.
False. Europe would be warmer than Canada because the Gulf Stream moves the warm water and air upward toward Europe.
