How many oceans on Earth: disputes about the exact number

Favorite question of all teachers of geography: "How many oceans on Earth does it exist?" In this case, it is possible to respond in various ways, in more detail understanding the structure of the hydrosphere of our planet. The water shell is the guarantee of life and prosperity on the Earth, therefore everyone should be at least superficially acquainted with the processes that occur in it. This article and many other interesting facts about the hydrosphere.

After long observations, all the scientists of the world came to the conclusion that the answer to the question of how many oceans on Earth exists is unambiguous - four. If you look at the history of hydrosphere research, you will see that the Indian Ocean was first discovered . It is rightly considered to be the warmest on Earth, because in the summer near the coast its waters can warm up to a record temperature of 35 ° C.

After the travel of Christopher Columbus, who was trying to find a way to India - the most attractive country for Europeans of that time - humanity learned about a new large water body. In honor of the Greek titan Atlanta, whom mythology endowed with steep temper and courage, the ocean was given the name Atlantic. This water object fully justifies the comparison with the hero of the myth, because at different times of the year he can behave absolutely unpredictably.

How many oceans are there yet? Among the unnamed earlier there were two: the Pacific and the Arctic. The Pacific Ocean, in fact, got its name by mistake, because during the trip around the world the great seafarer Magellan was very lucky with the weather. As a result, the researcher thought that the ocean has a gentle temper, but this is far from being the case. Near the western shores of North America and near the Japanese islands there are often tsunamis.

The Arctic Ocean is the quietest of the largest water bodies of our planet, and also the coldest. In its waters, not so many fish and plants, because not all representatives of flora and fauna can withstand the harsh conditions of life in it.

There was a period when some scientists asked the question: "How many oceans on Earth?" - answered: "Five." They isolated another water body, which washes the coast of Antarctica. He was given the name Southern, but its boundaries are so fuzzy that over time, compilers of geographical maps have ceased to designate this ocean.

This is well-known information about how many oceans on Earth. Many space researchers believe that the hydrosphere could be on other planets of the solar system. So, for example, scientists around the world ask the question: "How many oceans on the planet Mars once existed?" They have not yet found an answer, but if the hydrosphere there was still, then most likely on the next planet millions of years ago could also To inhabit living organisms.

The oceans form an unbroken chain on our planet, the constituent parts of which are all the above water objects. He is the source of life, therefore, humanity must preserve such an important resource as pure water. Thanks to the competent distribution of these stocks, people guarantee their normal existence, as well as reducing the likelihood of various natural disasters.
