How were the oceans and seas formed?

Have you ever stood on a beach and wondered where all the water in the ocean or sea came from? Well, oceans and seas were formed long, long ago, before there were any animals or people on earth. The earth was made up of red hot rocks then and when the rocks cooled, they gave off steam. This steam became rain, which fell and filled up the hollows and deep holes in the earth’s surface. The water that was collected in this way became the seas and oceans. The high parts of the earth remained as dry land.
