Oceans of the world

oceans of the world
The natural water area belongs to the most partthe surface of the planet Earth, and the oceans of the world and the sea in this water area occupy about 97% (or about 70% of the surface of the entire Earth). The rest of the water area belongs to rivers, lakes, reservoirs, swamps, glaciers.

Pacific, Atlantic, Arctic and Indian - the oceans of the world, called scientists until 2000. Since 2000, the Southern Arctic was designated as the fifth ocean.

The deepest ocean in the world and the most extensive -Quiet. Its area is larger than the area of ​​all the land on the planet, and in its abyss is the deepest place on earth - the Mariana Trench. Waves of the ocean wash the western shores of South and North America, Australia, the eastern shores of Asia. In the Northern Hemisphere, it joins the Arctic Ocean through the Bering Strait, and in the southern hemisphere it reaches the shores of Antarctica. Very many of its banks have hilly and mountainous terrain, and within its water area there is a large number of islands.

Naturally, all the oceans of the world have a verydifferent character. So, it should be noted that the Pacific Ocean is famous for the frequent tsunamis that reach fifty meters high on some shores, and also because it accounts for more than half of the entire biomass of water depths.

The second largest is the Atlantic Ocean.Its bottom is quite complex, with many basins. Unlike the Pacific Ocean, the Atlantic does not have in its water area as many islands. In the north, it meets with the Arctic Ocean. The Atlantic is known for the fact that the area of ​​the rivers flowing into it is much larger than the area of ​​the rivers that flow into any other ocean. In addition, its banks are very indented and washed by waves of a large number of famous seas.

Oceans of the world, as mentioned above, includeitself also the coldest: the Arctic. It is located beyond the Arctic Circle. Almost all of its area is covered with ice almost all year round. The waters of the ocean are strategically very important, because allow you to get from America to Russia on the shortest path. Especially this fact was important during wars. Near the coast, the SFO forms many seas, is connected to the Atlantic and Pacific oceans. Because of the constantly low temperature, the animal and plant world of its waters is represented by a few species.

The Indian Ocean by the size of the water areabelongs third place. It adjoins Africa and Australia, Asia and Antarctica. Its waters are washed by the largest islands: Madagascar and Sri Lanka, as well as such beloved by many tourists Maldives, the Seychelles, the island of Bali. His waves, twisted into ideal pipes, are loved by many surfers, and his bowels are very rich in deposits of natural gas, oil.

As already mentioned, also in the oceans of the worldinclude the Southern Ocean. Otherwise it is called Antarctic. With its waters it ishes the coast of Antarctica, includes part of the southern waters of the Pacific, Atlantic and Indian oceans. In the practice of navigation, the name of this water area practically did not take root, in view of the fact that it is not included in any manuals on the relevant topics. Meanwhile, this area occupies the fourth place among all oceans in terms of area.
