THE WORLD’S OCEANS
THE OCEANS OF THE WORLD
The oceans were formed around 4,000 million years ago.
Water occupies
71% of its surface.
Then, when the tectonic plates separated, they divided the five big oceans that we currently know:
The Pacific
The Atlantic
The Indian
The glacial Arctic
The glacial Antarctic.
- CONTAMINATION
There are
delimited areas, close to the continents or even interiors, which form the regional seas.
Los océanos contienen el 96% del agua líquida de la Tierra. Significa que solo el 4% es agua dulce.
They are the
largest lungs on the planet, since they provide more than half of all the oxygen in the atmosphere.
Of the 70% of the planet surface that is covered by the oceans, the human beings have just explored a 10%.
The industrial wastes, the radioactive material (Fukushima), the oil
spills, contributed to deteriorate the marine system.
- THE PACIFIC OCEAN
The Pacific Ocean, which Ecuador is riparian, it is the oldest, most extensive and deepest in the planet. Its surface is double than the Atlantic.
Its latitudinal extension (between the coasts of Indonesia and Peru) is almost half the circumference of the globe, with 19,800 km.
Its eastern shores are Asia and Australia and its western shores are America.
In that seabed is also located the deepest place in the world, Marianas Trenches (11.000m), being 25% higher than the Everest
In its area, there are about 25 thousand islands.
The Pacific influences the climate of the entire planet through what is known as "El Niño" phenomenon that occurs annually.
In addition, 90% of the world's active volcanoes, placed just at the edge of the plates, form what is known as the "Ring of Fire of the Pacific"
- THE ATLANTIC OCEAN
The Atlantic Ocean extends from Europe and Africa.
It is the second most extensive ocean and occupies
16% of the surface of the Earth.
Its maximum depth is in the Puerto Rico trench
The Atlantic and the Pacific are the only oceans that communicate with the other four.
- THE INDIAN OCEAN:
It bathes the eastern coasts of Africa, the Arabian Peninsula and those of South Asia
Being its width of 10,000 km.
Its surface represents 20% of the world's marine spaces; its
volume is estimated at 292'130,000 km.
It is the warmest and the one with more salinity.
- THE ARCTIC OCEAN
The Arctic glacial ocean, also known as the Arctic Sea
Is found
around the grounds of the North Pole, forming a circular pond surrounded by land masses.
It is the least deep and smallest ocean in the world.
It has two climatic zones: the arctic polar and the sub polar.
The ownership of the waters of this ocean is very disputed by several powers, it is known that the Arctic has large deposits
of natural gas and oil.
The Arctic ecosystem is very fragile; its plant resource is the phytoplankton of the sea, because on most of the land nothing grows.
- THE ANTARCTIC OCEAN
The Antarctic glacial ocean, also known as Southern or Southern Osseous
Extends from the Antarctic coast, to 60% south.
The water temperature varies from -2 to 10 ° C.
There are cyclic tons, which move around the Antarctic in the east direction.
Fishing is prohibited for the most part of the ocean and where permitted, is strictly controlled.
