Where might you find a gyre?

• Moving in a circle in the South Atlantic Ocean, between South America and Africa

• Moving in a straight line in the North Atlantic from North America to Europe

• Moving in a triangular pattern 500 meters beneath the surface of the South Pacific Ocean

• Moving in one long loop through all of the world's oceans

Surface currents are mainly caused by prevailing winds. What is the best synonym for "prevailing?"

• Gentle

• Fierce

• Permanent

• 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 wind to curve left in the northern hemisphere, and right in the southern hemisphere

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

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

Which word describes the speed at which the "Global Conveyor Belt" moves?

• Rapid

• Supersonic

• Gradual

• Variable

In the movie, Tim and Moby's raft is probably being moved by:

• Surface currents

• The Global Conveyor Belt

• The Coriolis Effect

• The Antarctic circumpolar current

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 the largest part of the Global Conveyor Belt

• The Gulf Stream is the only part of the Global Conveyor Belt located in the northern hemisphere

• The Gulf Stream is one segment of the Global Conveyor Belt
