The Oceans takes up 7 10ths of the earth. But the ocean is actually only 96.5% water. The other 3.5% is 2.75% Sodom chloride and 0.78% other things.

The ocean contains 360 quintillions gallons of wate

r. (And just so you know; a quintillion is a billion billions which is 6 sets of 3 zeros or18 zeros.

Gallons of water int the ocean:

1,000,000,000,000,000,000, times 360. That's a lot of water.

One cubic mile of ocean water contains:

** 4.5 billion tons of water**

** 128 million tons of Sodium Chloride (table salt)**

** 18 million tons of magnesium chloride**

** 8 million tons of magnesium sulfate (Epsom salt)**

** 6 million tons of calcium sulfate**

** 4.2 million tons of potassium chloride **

** 470,000 tons of calcium carbonate**

** 47,000 tons of rubidium**

** 1,400 fluorine**

** 1,400 tons of nitrogen**

** 470 tons of zinc**

** 380 tons of phosphorous**

** 380 tons of arsenic **

** 94 tons of iodine**

Any way that's a lot of things in one cubic mile of ocean.
