what is the differance between an ocean and a sea?

Answer 1

There can be various definitions of seas and oceans, and sometimes the term sea is used to indicate an ocean. But in general oceans are larger, and there are officially only 4 of them (Arctic, Indian, Atlantic, and Pacific).

There are far more seas than oceans (and far more than 7 of them despite the old expression of "sailing the 7 seas"). Oddly, seas are not necessarily surrounded by land. In particular, the Sargasso Sea is a defined area within the Atlantic Ocean, so it is completely surrounded by water.

Bottom line: Memorize the names and locations of the oceans, and keep in mind that different people may use the term "sea" in different ways.

A couple "technical" facts:
1. The Caspian Sea is actually a lake (it is an inland body of fresh water).
2. Technically, there are 7 oceans: Arctic, Indian, North & South Atlantic, North & South Pacific, and the Southern Ocean (surrounding Antarctica). But we generally combine the two Atlantic Oceans into a single ocean, do the same with the Pacific, and we don't treat the Southern Ocean as being separate from the Atlantic, Pacific, and Indian Oceans, even though it has its own current flows.

Answer 2

A S E A is a large expanse of saline water connected with an ocean, or a large, usually saline, lake that lacks a natural outlet such as the Caspian Sea and the Dead Sea. The Sea of Galilee is a small freshwater lake with a natural outlet, but the term was applied to it anyway

whereas an ocean is one of the large bodies of water into which the great ocean is regarded as divided, as the Atlantic, Pacific, Indian, Arctic and Antarctic oceans.

Answer 3

Geologically, an ocean is an area of oceanic crust covered by water. Oceanic crust is the thin layer of solidified volcanic basalt that covers the Earth's mantle where there are no continents.

A sea is a large expanse of saline water connected with an ocean, or a large, usually saline, lake that lacks a natural outlet.

The words ocean and sea are used interchangeably, yet a sea is a body of water that is much smaller than an ocean.

Answer 4

Ocean:
1 a : the whole body of salt water that covers nearly three fourths of the surface of the earth b : any of the large bodies of water (as the Atlantic Ocean) into which the great ocean is divided
2 : a very large or unlimited space or quantity

Sea:
1 a : a great body of salt water that covers much of the earth; broadly : the waters of the earth as distinguished from the land and air b : a body of salt water of second rank more or less landlocked c : OCEAN d : an inland body of water -- used especially for names of such bodies
2 a : surface motion on a large body of water or its direction; also : a large swell or wave -- often used in plural b : the disturbance of the ocean or other body of water due to the wind
3 : something likened to the sea especially in vastness
