Does it Matter that all the Oceans are connected?

• Mix cold water with warm water.

• Mix shallow water with deep water.

Where did the dry land come from?

-- It came from the ocean!

Gen. 1:9-10 And God said, "Let the waters under the heavens be gathered together into one place and let dry land appear." And it was so. God called the dry land Earth, and the waters that were gathered together he called Seas. And God saw that it was good.

But we are talking today about the oceans.

So let's talk about the Arctic Ocean…

What would happen if the Arctic Ocean's ice cap all melted?

Would the Ocean level rise?

What would happen if the Antarctic ice cap all melted?

Would the Ocean level rise?

Why might there be a difference?

An Experiment…

Materials:

• A large glass pot

• a paper plate to cover the pot

(punch a hole in the middle)

• Ice cubes

• A fine-point marker.What happens to the water level as the ice melts?

Summary Questions:

Why is the Ice Cap so thin at the North Pole?

- Because the ice is warmed by the Arctic Ocean!

How can that be?

- Because the Arctic Ocean is warmed by global currents.

Why is the Ice Cap so thick at the South Pole?

- Because it is over land, which is not warmed by global currents.

Now you know one thing that the oceans do: They carry warmth to the Northern parts of the earth.
