Four-fifths of the southern hemisphere and also the more than three-fifths that the northern hemisphere are under water. The Pacific, 70 million square mile in area, is virtually circular in shape and also covers nearly half the earth"s surface. The Atlantic, at 36.3 million square miles, forms a wide S through the two sides almost matching. The Indian Ocean forms a huge triangle v the Indian peninsula protruding through the upper apex. The Arctic Ocean, through its sheathe of floating ice, has actually an area of just 3.7 million squares miles and also is practically surrounded by land.

After looking roughly the web and also reference books, I discovered that the mass of the oceans is not always given in kilograms (kg). Few of the worths were provided in grams and also I had actually to transform them to kilograms by multiplying by 1000. One of the web page didn"t have the mass of the oceans, but it did have their combined volume. For this reason I had actually to calculation the massive by making use of the formula D=m/V, wherein D is density, m is mass, and V is volume. The thickness of s water is around 1000kilogram per cubic meter. Among my sources had neither mass nor volume, yet area in squares kilometers and also depth inmeters. To acquire the mass, i multiplied area times depth, times 10003 to obtain a an outcome in kilograms.

After spring up all the sites and the information I gathered, i have discovered that the massive of the human being oceans is around 1.4×1021kg.
