If a man in a spaceship looked down at the earth, he would see mainly water. He might think that the earth was one giant ocean with little land.
Nearly seven-tenths of the earth's surface is covered by water. One ocean, the Pacific (
太平洋), has an area of 63 million square miles.Many years ago people thought that the land under all this water was flat. Now they know that this is not true. There are as many mountains under the sea as there are on the land.
At first, there was very little salt in the sea. The salt was brought into the, sea by rivers. It is possible to measure the age of the earth by measuring the amount of salt in the sea. Scientists can calculate how many years it took for this amount of salt to be carried from the land into the sea.
