There is only one ocean It is divided into five different parts: the Pacific, Atlantic, Indian, Antarctic, and Arctic Oceans There are also many other smaller seas, gulfs and bays which form part of them Altogether they cover 75 percent of the earth’s surface For centuries, people have been challenged by the mysteries that lie beneath the ocean However, today’s scientists have overcome many of the challenges of the depth by using modern devices They send submarines to investigate the seabed and bring

samples of marine life back to the surface for further study Satellite photographs provide a wide range of information,

including water temperature, depth and the undersea populations If modern technology did not exist, we would never have such

precious information Marine plants and animals fall into three major groups Some of them live on or depend on the bottom like the starfish Some are swimming animals such as fishes and

sharks that move independently of water currents while others are tiny organisms that are carried along by the currents like the
