what is the difference between oceans and seas?

Answer 1

the difference between ocean and sea is the size



Oceans ARE bigger than seas
But a sea is more or less enclosed and separated from the larger ocean by land.

sea is generally considered to be smaller than an ocean. One definition of "ocean" is: a great body of interconnecting salt water that covers 71 percent of the Earth's surface. There are four major oceans—Arctic, Atlantic, Indian, and Pacific. However, some sources do not include the Arctic Ocean, calling it a marginal sea. The term "sea" is often assigned to saltwater areas on the margins of oceans, such as the Mediterranean Sea situated beside the Atlantic Ocean.

Answer 3

The terms are sometimes used interchangeably, with sea being used to describe an ocean. Oceans are generally the huge bodies of water (Pacific, Atlantic, Artic etc.) while seas are smaller bodies partially surrounded by land that are connected to the oceans (Dead, Red, Black, Baltic, etc)
