Only 30% of Earth’s surface is exposed land. the rest is covered by a huge body of salt water with a volume of more than 1 billion cubic kilometers: the world ocean. Twice a day, the oceans of the globe rise and fall by several meters. Tides are caused by the gravitational pull of the Moon , and to a certain extent of the Sun , on our planet. the seas and oceans also move in waves —undulations of the surface of the water generated by the wind. Ocean currents , on the other hand, are movements of huge masses of ocean water along very precise routes.
