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.
