Shifting
What effect does the Earth's rotation have on surface currents?
It causes wind to curve right in the northern hemisphere, and left in the southern hemisphere

It causes north-south movement in the northern hemisphere, and south-north movement in the southern hemisphere

How does warm water at the surface of the ocean become colder?
Icebergs from polar regions melt in it
It radiates heat into the atmosphere
Snow, hail, and sleet fall into it in polar regions
Colder water from below bubbles up and cools it off
What is the relationship between the Gulf Stream and the Global Conveyor Belt?
They are unrelated, since the Gulf Stream is a surface current and the conveyor belt is a deep-water current

The Gulf Stream is one segment of the Global Conveyor Belt
