1. How many oceans are there? 1? 3? 4? 5? 7? Oceans

2. Does it Matter that all the Oceans are connected? Mix cold water with warm water. Mix shallow water with deep water. Smooths out the temperature. } Currents Blue = cold and deep Yellow = warm and shallow

3. 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. Sedimentary Rock Beginning

18. 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. Summary
