What is the difference between ocean and seas ?

The word 'ocean 'implies the large water bodies of the world, namely, the pacific, Atlantic, Indian, and Artict, as well the Antarctic oceans where we find icebergs. Smaller seas are separated from the ocean by island chins or underwater ridges which are called 'bordering seas '.These include the North sea,the Baltic sea, the Mediterranean sea, and the Caribbean sea. The bordering seas and the oceans have some common pictures:both contain salty 🧂water and restless seabeds. But there are also differences in the variety of plants and animals living in them and the Strom tides -the tides that lash  the coast of the north sea are hardly found along the pacific coast. 🤔
