| Almost three quarters (71%) of the surface of the Earth is
covered by ocean. This global, interconnected body of salt water is divided
by the continents and larger archipelagos into five oceans as follows:

Smaller regions of the oceans are known as seas, gulfs, straits, etc What Is Salt Water?ll water, even rain water, contains dissolved chemicals which scientists call "salts." But not all water tastes salty. Water is fresh or salty according to individual judgment, and in making this decision man is more convinced by his sense of taste than by a laboratory test. It is one's taste buds that accept one water and reject another. |
