Question

Is there a difference between "Ocean" and "Sea"?

Answer 1

You've heard of "one world?" Well, technically, all the world's oceans and seas are part of one continuous mass of seawater. But because the ocean is so big, humans have divided it up and named the different parts. There are five oceans and several dozen seas.* Seas are usually smaller than oceans and are partially enclosed by land. But otherwise, they're exactly the same thing.



Although the terms "ocean" and "sea" are often used interchangeably, a 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 4

A sea can be any large body of water and can either be salty or fresh.  The ocean refers to the body of salt water that covers the earth.  The Atlantic, Pacific, Arctic, Antarctic and the Indian Ocean are all one body of water.

Answer 5

A sea is an expanse of salt water partially bounded by land and shallower than an ocean.

An ocean is one of the five vast,deep,open expanses of salt water.They are Pacific,Atlantic,Indian,Southern and Arctic.
