The Most Fascinating Facts About The Largest Living Space Inhabited By Living Organisms In The Universe
Our planet s oceanic divisions – the Atlantic, Pacific, Indian, Arctic, Antarctic (Southern) Oceans – form the largest part of the Earth s hydrosphere (over 97% of the Earth s water) and approximately 71% of the Earth s surface is occupied by the oceans. Only 5% of the Earth s oceans has been explored so far. The exact origin of our oceans is unknown, but scientists believe that they have formed in the Hadean period, the first geologic eon on Earth. Scientists also believe that the oceans may have been the impulse for bio genesis, the natural process by which life emerges from inorganic matter, referring to the origins of life on Earth.
