THE WORLD’S OCEANS - Coggle Diagram

- - - - 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.

  - - - The industrial wastes, the radioactive material (Fukushima), the oil
        spills, contributed to deteriorate the marine system.
        
        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.

    - - 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.

      - 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.
- - - - 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.
- - - - 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.
