What is the difference between an ocean and a river?

Answer 1

Ocean :
The entire body of salt water that covers more than 70 percent of the earth's surface.
Ocean is subdivided into four major units that are separated from each other by the continental masses.

River:

A large natural stream of water emptying into an ocean, lake, or other body of water and usually fed along its course by converging tributaries.
stream of water larger than a brook or creek. Land surfaces are never perfectly flat, and as a result the runoff after precipitation tends to flow downward by the shortest and steepest course in depressions formed by the intersection of slopes. Runoffs of sufficient volume and velocity join to form a stream that, by the erosion of underlying earth and rock, deepens its bed; it becomes perennial when it cuts deeply enough to be fed by groundwater or when it has as its source an unlimited water reservoir, for example, the St. Lawrence flowing from the Great Lakes.

Answer 2

An ocean is a large body of salty water constituting a principal part of the hydrosphere.
A river is a large natural stream of fresh water (larger than a creek), that usually flows into the sea !

Answer 3

Ocean
The intercommunicating body of salt water occupying the depressions of the earth's surface, or one of its major primary subdivisions, bounded by the continents, or the equator, and other imaginary lines. A sea is subdivision of an ocean.

Definitions of river on the Web:

a large natural stream of water (larger than a creek); "the river was navigable for 50 miles"

A river is a large natural waterway. It is a specific term in the vernacular for large streams, stream being the umbrella term used in the scientific community for all flowing natural waterways. In the vernacular, stream may be used to refer to smaller streams, as may creek, run, fork, etc.

Answer 4

An ocean is salty and has tides. Rivers flow and are usually fresh water. Next time you have a real brain teaser why don't you try the Websters Dictionary.
