How do we distinguish the boundaries of adjacent bodies of water? in particular, the oceans?

I think what you mean is, if we had to draw lines differentiating the different oceans and bodies of water, where would we draw these lines? \n\nUnfortunately, I dont think there is any real correct answer.\nThese boundaries are kind of ambiguous and flowing....just like the oceans themselvess! Oceans aren't like countries, which have set boundaries established by wars and treaties, etc. Oceans flow into each other and are all connected. The best we can do is approximate. \n\nGood question, though.

In the northern hemisphere, the overall ocean current is clockwise.  That means, on the West Coast of the USA, the water is moving down from the Arctic (brrr!), while on the East Coast, it is moving up from the equator (ahhhh!).  But that's just the coastal United States.

Side view could be profile; strip of land is isthmus (strait is actually water)

The Earth's oceans are all connected to one another. Until the year 2000, there were four recognized oceans: the Pacific, Atlantic, Indian, and Arctic. In the Spring of 2000, the International Hydrographic Organization delimited a new ocean, the Southern Ocean (it surrounds Antarctica and extends to 60 degrees latitude). \nSee map with location in\nhttp://www.enchantedlearning.com/subjects/ocean/

It is based on geographic location the colors of compass direction.\n\nIn older times The Red Sea was also called the Southern Sea.

OK, first geography is NOT geology *sigh*\n\nLook up carbon dating; you can either tell by the degradation of carbon or by basic layering (what's on the bottom is older than what's on the top).

map makers esentiallt did what is known as graphing.  what they did is basically take a piece of graphing pad marking out latitudes and longatudes respectively. they then took measurements as to where they were with a device known as a sextant which they use to determine thire position on the planet LAT/LONG by using the stars as they traveled they marked on the grid paper what thier lat/long was then simply connected the dots this technique can be used to mark coastlines  or if inland plot your course (eg make a line on the map known to be dry land) this course can then be translated to be the border between utah and montana for example the lines for borders between states were mostly arbatrary some were set forth by the gov't where the lines were to be drawn others may have been a natural boundary such as a river or other waterway.\n\ni hope that is what you were looking for

Istanbul. It depends on what you consider to be sea as there is no city literally split in half by deep ocean. If you consider any navigable saltwater strait that connects two sea sized bodies as "divided by sea" then Istanbul is divided by sea. The Black and Mediterranean Seas are connected by the Bosphorus, a strait around 1 mile wide.\nI really can't think of any others at the moment.\nCopenhagen is on a strait, maybe if Malmo,Sweden is considered a suburb then that too.

You should take a look here to see the formation of the ocean basins: http://www.mos.org/oceans/planet/change.html\nand then the next page, to see one theory on where the water comees from:\nhttp://www.mos.org/oceans/planet/cycle.html\n\nPerhaps a better answer is here:\nhttp://www.madsci.org/posts/archives/oct99/941236464.Es.r.html\n\nFurther discussion on the origins of all the water is given here:\nhttp://www.oceansonline.com/ocean_form.htm\nand under the "Origin of the oceans" title here:\nhttp://www.seafriends.org.nz/oceano/oceans.htm

Hi, \n\nThat would be national boundary!!\n\nThanks!!

Both r water bodies, But the name differs due to the area and the depth of water

The oceans are divided into two main zones: the pelagic and the benthic zones. The pelagic, the uppermost zone, is further divided into the euphotic or sunlit zone up to 660 feet, the dysphotic or twilight zone up to 3,300 feet, and the aphotic or midnight zone up to 20,000 feet.

youre both right.  the boundary is the line you want to draw.  then shade the up or down side.

Because the earth is round, and if you made your flat map a oval(circle), the oceans would connect and become one!
