Difference between Sea and Ocean
Sea and ocean are two different water bodies of saline water but people often use these two terms interchangeably while referring to a large body of saline water. We do agree that sea and ocean share a number of features but still, they are different from each other in terms of their area, depth and marine flora and fauna. Let us see how they differ from each other so that next time we do not confuse these giant water bodies with each other!
A sea is a water body of saline water. It is a part of the ocean and is partially enclosed by the land, i.e. it is located at the margins of an ocean, where it connects the ocean with the land. For example, the Bering Sea is the part of the Pacific Ocean and connects it with the land.
As seas are parts of the oceans they are smaller in size than the oceans. The top five largest seas in terms of their area are as follows:
Oceans are vast and continuous water bodies of salt water that cover more than 70 % of the total Earth's surface. All the oceans on the surface of Earth are interconnected and are considered as one World Ocean. This "World Ocean" is divided into five different oceans which are listed below in terms of their area, starting from the largest ocean to the smallest ocean.
Based on the above information, some of the key differences between sea and ocean are as follows:
