Ocean vs Sea
Ocean and sea are two terms that often look alike in their meanings but strictly speaking there is a lot of difference between them. The general idea is that a sea is smaller in size when compared to an ocean and hence it is considered a part of the ocean. It is interesting to note that sea is generally surrounded by masses of land. When compared with a sea, an ocean is huge in size. As a matter of fact, the 71% of water mass that covers the Earth’s surface is a one huge ocean. There are some other interesting facts about ocean and sea, which will be discussed in this article.
What is a Sea?
A sea is a small area of salt water, which is normally partially enclosed by land. A sea can be named as a small part of an ocean. It is a wonder that the world’s largest sea is very small when compared to the smallest ocean in the world. The largest sea in the world is the Mediterranean Sea and it is one-fourth of the world’s smallest ocean, the Arctic Ocean. As a matter of fact, there are a number of seas in the world.
The seas are shallower when compared to the oceans. The reason for the lack of depth in the case of seas is that they are close to land in general. When it comes to the existence of life, sea beds are growing places of plants and animals that depend on light. Another interesting fact about sea is that man can attempt to reach the sea bed with the help of scuba gear.
What is an Ocean?
According to the Oxford English dictionary, an ocean is ‘a very large expanse of sea, in particular each of the main areas into which the sea is divided geographically.’ From even this definition, you can understand that an ocean is bigger than a sea. In fact, according to this, several seas are collected together to make an ocean.
There are five oceans in the world. They are theArctic, Antarctic, Pacific, Indian and Atlantic Oceans.Unlike seas, oceans are unfathomable. When it comes to creatures and plants, you do not find plant life on the ocean beds. Moreover, they are laden with basic forms of life like the bacteria. The reason for the non-existence of plant life on ocean beds is that light cannot reach the depths of the oceans. When it comes to exploring the ocean bed, it will be very difficult for man to reach the depths of the ocean beds for he would find it difficult to withstand the pressure existing on the surface of the ocean beds. He would need the help of a special equipment called theBathyscaphe.
What is the difference between Ocean and Sea?
• An ocean is much larger in size than a sea.
• Generally, sea is partially enclosed by land.
• As a matter of fact, there are a number of seas in the world whereas there are only five oceans in the world. The five oceans are Arctic, Antarctic, Pacific, Atlantic and Indian Oceans.
• One of the primary differences between oceans and seas is that the seas are shallower when compared to the oceans.
• Oceans and seas show difference between them in terms of the life that exists on their beds too. Ocean beds are not so much full with life as sea beds as they are too deep.
• Reaching ocean bed is not so easy for man as reaching sea bed.

I think the answer is not always true. It depends on the context. If you travel on a ship from the US to Europe or vice versa, the term is “going overseas.” not over oceans! The same when a sailor sets sail the term is he is “going to sea” Not going to ocean. You also say Oceans are deep and seas are shallow, but again the term is “The Deep Blue Sea”. We also sail the 7 seas not the 7 oceans?
