The Gulf Stream

From memory: sketch the north Atlantic ocean, draw and annotate the cold and warm sections of the gulf stream.

Q: England is as far north as central Canada yet its climate is about the same as New York’s.   Explain why this is and why London is usually foggy.

The Gulf Stream is driven by the difference in water temperature between waters near the equator and waters near the north pole.

The Gulf Stream is a convection current.
