Oceans and bays are enormous bodies of water. Oceans are the most substantial water bodies on the globe; however, a bay is a form of water area that is bordered by land. Generally, a bay is a water body that is surrounded by land on three sides. Five oceans cover about 71% of the earth's surface. Bays are often an inlet in a lake or a more extensive water body.
As the bay is enclosed by land, one can come across calmer water than the oceans. Large bays can be called sea, gulf, bight, or sound, and the smaller bays can be called fjords. Oceans have more depth than the bay. The major bodies of oceans are the Pacific, Atlantic, Indian, and Arctic. On the other hand, there are numerous bays, and two of the well- known bays are Hudson Bay and Bay of the Bengal. Oceans possess higher waves than bays.
