Part of the ocean whose penetration - what is it?

often in a variety of test tasks or even crosswords found a job here, "part of the ocean whose penetration - is ..." The most common answer to this question is "Sea".But is it really?Before answering this question, let us consider some of the general part is the ocean.

Oceans

All the water that covers most of the earth is called the world's oceans, the largest component of which is the Pacific, Indian, Atlantic and Arctic oceans.Their total area of ​​just over 361 million square kilometers.Visible lines that would be shared between an ocean, there is little.Therefore, the division made quite arbitrarily by the waterfront, benthic terrain, systems of currents, water distribution characteristics.

Sea

part of the ocean whose penetration, though slightly (in most cases), called the sea.Almost all of them are marked islands, surface elevations, and so on.Only the sea that has no shores - the Sargasso Sea, is part of the ocean, the land is not limited to any one of the parties.Sea area account for

about 10% of the world's oceans.Most huge area - Philippine.

from the open ocean sea distinguished by unique hydrological regime and some other features, resulting from a kind of insulation, the significant effects of the land and slow currents.

Sea are divided by location on the outskirts, located on the border of the land to the sea, inside, inside the continents, and inter-island, located in the ring, or some, sometimes contingent, fences, a group of islands.

Sea basin can be continental and oceanic, different way of occurrence of basins and hence depth.So, the mainland emerged as a result of increasing ocean water from melted glaciers.Ocean formed in places the faults of the crust.Basically - it mezhmaterikovye sea, with a fairly balanced basins.

coastline seas often uneven, with different twists and peninsulas.Along the coast of the island can be separated from each other by straits.

Bays

It is part of the ocean, whose penetration is deep enough.From the oceans slightly isolated.It can be divided into several types:

- Fjords.It is long and narrow bays, with substantial depth and steep banks.Lies in mountainous areas.Most often produced in areas of tectonic faults.

- Limani.This small bay formed by local estuaries, flooded by sea.

- Lagoon.Located along the coast, separated from his braids.

Sometimes bays divided by size.Champion in size - the Bay of Bengal.Its depth of 4519 meters, and the area - 2191 square kilometers.

There are cases where similar in size and the size of the reservoirs is called differently.For example, the Bay of Bengal has a similar area of ​​the Arabian Sea, the Red Sea area close to the Persian Gulf.The point here is that these objects are named in ancient times, when there were no clear definitions.Giving such a large geographical features new name does not make sense.

Straits

part of the ocean, whose penetration is deep enough.It has a relatively small width, shares a land or connects the reservoirs.

Straits divided into narrow and wide, long and short, deep and long.Also, there are flow passages and exchange.The flow for always in one direction.Sharing the same surprising variety of course on the opposite bank, or at different levels of depth.

So how is that part of the ocean, should be considered in each case, bearing in mind the other signs, other than the fact that it juts out into the land.After all, we already knew most of the parts of the land juts out into the ocean, although some of them more, some less.
