ainfall:   The ocean is the source of more than 80 percent of all the evaporation of water on Earth. Almost all of this evaporated water falls back on the ocean as rain and some falls on land. But the evaporation and rainfall patterns vary across the various oceans; more water evaporates from the Atlantic and Indian Oceans than falls as rain. The northern Pacific Ocean, especially near the tropics, receives more rain than the amount that has evaporated.



emperature: The temperature ranges from freezing at the pole and in deep waters and warm in tropical, the clear average is at 39 degrees.
