The largest ocean in the world. Find out which is the largest ocean
On planet Earth there are five huge majestic Silent, Indian, Arctic and Southern. What is the biggest ocean you think? Of course, Quiet! The area of this giant container of water is 178.6 million km2. That is one third of the surface of our planet and almost half the area of the entire World Ocean. Imagine that on such a vast territory all earthly continents and islands could freely accommodate. And the biggest ocean of the Earth is the deepest. Its average depth is 3984 m.The Pacific Ocean "owns" the seas, islands, volcanoes, its waters are home to a huge number of living beings.No wonder this "meek" is called the Great. About the Pacific can talk endlessly. Unfortunately, our capabilities are limited to one article, but we will try to provide in it the maximum possible information about the great water Titan.
Where is the Pacific Ocean
Let's take a globe or a map and see where the largest ocean of the planet is located. Look: in the west it stretches between Australia and Eurasia, in the east - between North and South America, in the south it approaches the Antarctic itself.
On the Bering Strait (from Cape Peek in Chukotka to Cape Prince of Wales in Alaska), the Pacific Ocean is bordered by its counterpart - the Arctic Ocean. Along the western coast of Sumatra, the northern outskirts of the Malacca Strait, the southern shores of the islands of Timor, New Guinea and Java, through the beautiful Torres and Bass Straits, along the coast of eastern Tasmania and further up to Antarctica, the border with the Indian Ocean stretches from the Antarctic Peninsula, further along the dangerous thresholds between the Shetlands to the Tierra del Fuego. The Great Ocean stretches from north to south by about 15.8 thousand km., And from east to west - by 19.5 thousand km.
A bit of history
The largest ocean in the world received the name "Quiet" with the light hand of the famous Spanish and Portuguese navigator Magellan. It was he who, in 1520, was the first to venture on a journey through uncharted waters.For all the time of the sea route, which lasts more than three months, the ship of Magellan did not get into any storm, the skies were surprisingly supportive of the brave sailors, which is rather strange, because it is in these places that the strongest and most ferocious typhoons and hurricanes are born. World Ocean.
And the pioneer of the Pacific Ocean is considered to be the Spaniard Vasco Nuñez de Balboa. This conquistador was the first to be lucky enough to see new, previously unseen ocean expanses. And this happened in 1510 in this way: de Balboa founded a settlement on the shores of the Dariensky Bay, suddenly rumors flew to him about a fabulously rich country, which can be reached if you sail the vast sea in the south. Balboa detachment immediately set off and after 4 weeks went to the shore of the Pacific Ocean. Of course, he had no idea about the fantastic size of the open water space. Balboa thought it was the sea.
31 seas join the largest ocean on Earth. Here are their names:
- South China.
- New Guinea.
- Sea Sava.
- Sea Halmahera.
- Solomon Sea.
- Sea of Bali.
- Sea Banda.
- Sea Seram.
- East China.
- Sea Amundsen.
- Bering Sea.
The largest ocean of our planet washes the shores of 5 continents: Australia, Eurasia, South and North America and Antarctica. And there are more than 25 thousand islands with a total area of 3.6 million km.2. Most of them are of volcanic origin.
The Aleutian Islands are located in the northern part of the Pacific Ocean, Japanese, Kuril, Philippine, Sakhalin, New Guinea, Tasmania, New Zealand, Large and Small Sunda in the western part of the world, and a great many small islands are scattered in the southern and central regions. The islands in the western and central parts of the ocean form the Oceania region.
The largest oceans of the world can radically influence the weather on the entire planet. What can we say about such a giant as the Pacific Ocean! There are typhoons of terrible destructive power, tropical storms, huge tsunamis, threatening great disasters for many states.Scientists are closely watching all the changes in his mood, and it is not so easy to do that, because the thousands of kilometers of ocean water stretching from north to south are divided into different climatic zones, from cold Antarctic to hot equatorial.
The widest climatic zone of the Pacific Ocean is equatorial. It is located between the Tropic of Capricorn and the Tropic of Cancer. Here, the average temperature is never below +20 degrees. For these places, the characters are frequent tropical cyclones. To the north and south of the equatorial zone are tropical and subtropical climatic zones, and then go moderate, bordering the circumpolar zones. Antarctica has a significant impact on the temperature characteristics of ocean water. In equatorial and tropical zones, a lot of rain falls, approximately 3000 mm per year. This value is much greater than the amount of evaporated moisture from the ocean surface. 30 thousand m2fresh water enters the Pacific every year thanks to the many rivers flowing into it. These two factors lead to the fact that the surface waters of the Pacific Ocean are less saline than in the Atlantic, Indian, etc.
The bottom of the Pacific Ocean has an extremely diverse relief. Deepwater basins and troughs are located in the center of the Pacific Basin. And in the west is the deepest place in the entire World Ocean - the Mariana Trench. Huge areas of the bottom are covered with volcanic products containing cobalt, nickel, copper. Separate sections of these deposits are about three km thick.
At the bottom of the Pacific Ocean there are volcanoes and several long chains of high seamounts. These are the mountains of the Emperor, the Hawaiian Islands and Louisville. In the east of the ocean, where the East Pacific Rise is located, the relief is relatively flat.
The deepest ocean is 10,994 km. This place is located in the famous Mariana Trench - the most inaccessible and poorly known place on Earth. The Mariana Trench in the earth's crust forms a giant crack of 2550 km long and 69 km wide, resembling a crescent in shape. The water pressure at the bottom of the depression is almost a thousand times greater than at the surface. That is why immersion in this place even with the help of the most advanced deep-sea apparatuses presents an incredible danger and difficulty.
The study of the underwater world of the deepest point of the oceans is carried out mainly with the help of special robots. Only a few people managed to visit the bottom of the Mariana Trench. For the first time in the bathyscafe "Trieste", Don Walsh and Jacques Picard descended there. This event occurred on January 23, 1960. The next trip with the participation of man in the depths of the ocean was made in 2012. This was done by the famous American film director James Cameron. Thanks to these brave people, the knowledge of mankind about the mysteries of the Pacific Ocean has been greatly enriched.
The largest volcano in the world
The largest ocean in the world never ceases to amaze its researchers. In 2013, under its waters, an extinct volcano was discovered, the area of which is equal to 310 thousand km. This huge mountain range is called Tamu, and its dimensions are comparable only with the Mars volcano-giant Olympus.
Pacific flora impresses with its wealth and diversity. In the Pacific Ocean, as in all others, the laws of the spreading of wildlife work in climatic zones. Thus, in temperate and cold climatic areas, species diversity is poorer, but this is compensated for by the greater number of a particular plant or animal species.
Plant life is particularly active in tropical and subtropical ocean waters, between the coasts of Australia and Asia. There are giant territories occupied by coral reefs and overgrown with mangroves. The bottom flora of the Pacific Ocean has almost 4 thousand species of algae and more than 28 species of flowering plants. In the cold and temperate regions of the Pacific basin, algae from the laminaria group are common. In the southern hemisphere you can find giant brown algae, whose length reaches 200 m.
The Pacific Ocean - the largest ocean of the Earth - is the endless blue waters that are home to thousands of living creatures. Here is a place and the great white sharks, and very tiny clams. The Pacific fauna is richer than that in other oceans in its species composition almost 4 times!
Sperm whales, representatives of toothed whales, are widely distributed, there are several types of rare striped whales. The craft of both those and others is strictly limited. In the north and south of the Pacific, there are colonies of sea lions and seals. Walruses and sea lions live in the northern waters, now on the verge of extinction.Total Pacific fauna has about 100 thousand species of various animals.
As for the fish, there are a great many of them - about 2,000 species. Almost half of the world's total fish catch comes from the Pacific. Among all living creatures living in the Pacific Ocean, invertebrates dominate at very different depths. These are crabs, shrimps, various mollusks (squids, oysters, octopuses), etc. The tropical latitudes are rich in various species of coral.
The biggest ocean is loved by tourists all over the world. Still would! Who has not dreamed of at least briefly finding himself in heavenly places located in Polynesia, Hawaii and the Philippines? Fiji, Palau, Cook Islands are visited annually by huge crowds of people resting. In these places, the ocean water is clear, especially transparent and has a wonderful blue or green color.
In the equatorial part of the Pacific Ocean winds of moderate strength blow, and the water temperature is comfortable all year round. The beautiful underwater world, sandy white beaches, the friendliness of the local population, exotic flora and fauna are all signs of heaven on earth!
Pacific Ocean Trails
The largest ocean in the world plays a huge communication role. On its waters lies many trade and passenger sea routes connecting the states of the Pacific basin, as well as the coasts of the Indian and Atlantic oceans. The largest ports are: Nakhodka and Vladivostok (Russia), Singapore, Shanghai (China), Sydney (Australia), Los Angeles and Long Beach (USA), Vancouver (Canada), Huasco (Chile).
There are many interesting facts, thanks to which you can fight to understand which ocean is the largest and most amazing. About many you have already learned from this article. Here are some more interesting facts about the Pacific Ocean:
- If it were possible to evenly distribute all Pacific water over the surface of our planet, then it would cover the Earth completely with a water layer thickness of 2700 m.
- Nowhere in the world there are no such high waves as in the Pacific Ocean, which is why fans of extreme surfing especially respect it.
- The biggest fish in the ocean is the giant whale shark. Its length can reach 18-20 meters. And this giant prefers to live in the Pacific waters.
- The average speed of the devastating Pacific tsunami is about 750 km per hour.
- The Pacific Ocean can be proud of the highest tides. For example, at the coast of Korea, water at high tide can rise as much as 9 meters.
- The largest inhabitant of the ocean is the blue whale. Its weight sometimes exceeds 150 tons, and its length is more than 33 meters. In the Pacific, these rare animals can be found much more often than in other oceans.
Now you know what is the largest ocean on our planet, as well as how important it is for the Earth and for us - the people living on it. Unfortunately, due to unreasonable human activity, the waters of many parts of the Pacific Basin were polluted with industrial and oil wastes, many species of animal species were exterminated. All this threatens the fragile ecosystem of our planet, affects climate change. We can only hope that humanity will come to its senses, begin to behave more intelligently and learn to live in harmony with nature.
