Answer 1

The term “sea” is often used to refer to a smaller saltwater body that is partially enclosed by land. The word “ocean,” on the other hand, typically describes one of the five major interconnected bodies of saltwater on Earth, which are the Atlantic Ocean, Indian Ocean, Southern Ocean, Arctic Ocean, and Pacific Ocean.

The distinction between seas and oceans is not always strictly defined and can vary depending on geographical and cultural perspectives. In general, though, the term “sea” is commonly used to describe smaller bodies of saltwater, while “ocean” refers to the vast, open expanses of saltwater.
