OCEAN What is the Difference b/w Sea and Ocean

Oceans are large masses of saline water that make up a large part of the planet’s hydrosphere (although oceans have been discovered on other planets).

For many years there were only four known oceans, but in 2000 the International Hydrographic Organization added the Southern Ocean (also known as the Antarctic) to the list. The five oceans recorded so far are the Pacific, Atlantic, Indian, Antarctic and Arctic .

Approximately 72% of the Earth is covered by water. The oceans contain approximately 230,000 forms of marine life. The depth of these ranges between 13,000 and 35,000 feet.

Oceanographers divide the oceans depending on the zones and the physical and biological conditions present in them. They differentiate them based on depth, light, and other factors. 


A sea is a large body of saline water that may or may not connect to an ocean, although it is commonly connected. Sea is smaller compared to an ocean and shallower. It is believed to lack a natural outlet and is generally found close to the ground. In many cases it connects the land with an ocean .

The seas have waves that are not visible in the oceans. Among the best known include: the Mediterranean, Baltic, Bering Sea, Caribbean, Coral, Red and Black Sea.
