Elements of The Oceans:

General Information About Ocean Currents:

Ocean water is not the same everywhere an has different properties depending on the environment in which it is found. Fresh water has few dissolved salts and is found in streams and rivers. Water found in the ocean has a lot of dissolved salts in it and is called salt water. In areas where rivers flow in the oceans, called estuaries, the water is brackish and has a higher concentration of salts than the open ocean.

At the Earth's poles, the water is both very salty and very cold. These conditions make for very dense water. This water sinks and flows toward the equator along the ocean bottom. Water at the equator flows toward the poles near the surface to replace the sinking water. Both of these differences in temperature contribute to the global circulation patterns.
