Difference Between Ocean and Sea

Difference between Ocean and Sea is fundamentally important to understand, as one must be familiar with their surroundings and as Earth is 75% water, with only 25% land; it is important for everyone to understand the basic characteristics of the ocean and the sea, to separate it from one another. An ocean is nothing but a gigantic mass of water body present on earth, whereas the sea is defined as a small subset of the ocean, where it meets the land. Any mass of body that subsects and meets the land is called the sea. Thus, from this we know that a sea forms the smaller portion of the ocean and it is usually the area where the land meets the ocean. It also helps to know the classification of animal kingdom, as one can have a full understanding of the ocean aquatic life.
