A large part of the planet Earth’s surface belongs to the natural water area, and the oceans of the world and the sea in this water area occupy about 97% (or about 70% of the entire Earth’s surface). The rest of the water area belongs to rivers, lakes, reservoirs, swamps, glaciers.
Pacific, Atlantic, Arctic and Indian - the oceans of the world, named by scientists until 2000. Since 2000, the South Arctic has been singled out as the fifth ocean.
The deepest ocean in the world and the most extensive is the Pacific. Its area is larger than the area of all land on the planet, and in its abyss is the deepest place on Earth - the Mariana Trench. Ocean waves wash the western coast of South and North America, Australia, the eastern coast of Asia. In the Northern Hemisphere, it connects to the Arctic Ocean through the Bering Strait, and in the southern - it reaches the coast of Antarctica. Many of its shores have hilly and mountainous terrain, and within its waters there are a large number of islands.
Naturally, all the oceans of the world have a very different character. So, it should be noted that the Pacific Ocean is famous for frequent tsunamis, which reach fifty meters off some coasts, as well as the fact that it accounts for more than half of the total 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 so many islands in its water area. In the north, it meets the Arctic Ocean. The Atlantic is known for the fact that the area of rivers flowing into it is much larger than the area of rivers that flow into any other ocean. In addition, its shores are very indented and washed by the waves of a large number of famous seas.
The oceans of the world, as mentioned above, also include the coldest: the Arctic Ocean. It is located beyond the Arctic Circle. Almost its entire area is covered with ice almost all year round. Ocean waters are strategically very important, because allow you to get from America to Russia along the shortest path. This fact was especially important during the wars. Near the coast, the Arctic Ocean forms many seas, connected to the Atlantic and Pacific Oceans. Due to the constantly low temperature, the animal and plant world of its waters is represented by a few species.
The Indian Ocean is the third largest water area. It is adjacent to Africa and Australia, Asia and Antarctica. Its waters are washed by the largest islands: Madagascar and Sri Lanka, as well as the Maldives, Seychelles, and the island of Bali , so beloved by many tourists . Its waves, twisting into perfect pipes, are loved by many surfers, and its bowels are very rich in deposits of natural gas and oil.
As already mentioned, the Southern Ocean also began to be included in the oceans of the world . Otherwise, it is called Antarctic. With its waters, it washes 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, due to the fact that it is not included in any manuals on the relevant topic. Meanwhile, in terms of area, this water area occupies the fourth place among all the oceans.
