The deepest ocean of the earth is Indian. The deepest river The deepest cave

There are five oceans in the world - Atlantic Ocean, Arctic Ocean, Indian Ocean, Pacific Ocean and South ocean. Each of these oceans is characterized by a certain area, depth and size. Want to know which ocean is the deepest ocean in the world? The largest and most deep ocean in the world is the Pacific Ocean. It covers an area of ​​65,300 thousand square miles or 169,200,000 in square kilometers. The ocean extends from the North Arctic Ocean to the Southern Ocean.

Geographically, about 46 percent surface water lands belong to the Pacific Ocean. In other words, it accounts for up to 30 percent of the earth's surface. Interesting fact volume Pacific Ocean is believed to be about 622 million cubic meters. The Pacific Ocean is divided into two parts, the North Pacific and South part Pacific Ocean, the division occurs along the equator.

Speaking of the average depth of the Pacific Ocean, oceanographers suggest that it will be about 13,215 feet. The main reason is the collision of oceanic plates in this region. Two converging oceanic plates collided with each other, and one of them moved down to the mantle layer. This collision led to the formation of the Mariana Trench - 35,797 feet or 10,911 meters.

Once I read a book that collected the legends of the inhabitants Pacific Ocean. According to one of them, in the deepest place lives giant octopus, whose tentacles hold the whole world. Who knows, because the deepest place has not been finally explored...

The deepest ocean in the world

Certainly this is a great Pacific Ocean- the oldest and largest of all on the globe. Its area is so large that it can freely accommodate all the islands and continents. The widest place in the area equator, and the outer outline of the ocean resembles an oval. The deepest section Mariana Trench. This place is little studied, because the depth reaches 11000 meters.

Above all, this ocean contains the largest number islands. Some are uninhabited and some are inhabited natives whose culture is very unique. The settlement of the islands began around 7000 years ago when the Asian natives migrated to the islands. Due to the insignificance of the population and the dispersal of the islands, they did not succeed at all in creating civilization.

Mysteries of the Pacific

In addition to the fact that the ocean is the deepest and most full-flowing, it is also "an ocean of mysteries". Within its boundaries are concentrated a lot of amazing and mysterious places . Here are some of them:

• Mount Kasimakaisan;
• sea ​​of ​​the Devil;

Mount Kasimakaisan. Despite the rather impressive height - 4000 meters, this mountain was known only to a few. And all because it seamount located close to the islands Japan. It was discovered in 1936, and according to the results of recent studies, it turned out that the peak was split in two.

Sea Devil. This place is no less mysterious than the enigmatic Bermuda Triangle . The sailors who sailed in this zone repeatedly recorded strange noises that came from the depths. Sometimes it was something like a rumbling, and sometimes a deafening gurgle. Some sounds last a few minutes, and some have been heard for many years. Scientists believe the sounds could be caused by eruptions, icebergs, and even unknown sea animal.

Easter Island. In the southern part of the ocean there is a popular island due to its idols. In total there are about 1000 statues carved from solid rock. The largest has a height 23 meters, and its weight is more 16 Tons. Each of them is unique and decorated with a special pattern. It is assumed that the statues were erected in honor of a deity or dead leaders, but the exact purpose is unknown.

My element is water. As a child, my favorite cartoon was The Little Mermaid, in my games I imagined myself as an inhabitant sea ​​depths. Now that I'm older, I like movies about pirates, divers and underwater treasure hunters. The ocean fascinates me. And the fact that it has not been fully explored only fuels interest. And so I thought which ocean is the deepest And what secrets does he keep?

The deepest ocean is the Pacific

The Pacific Ocean is the most-most on our planet. He largest in area And deepest. It is the most violent and the most dangerous. It's surprising that it has such an inappropriate name. The fact is that Ferdinand Magellan, who gave the ocean its name, crossed it during the calm season and never got into a strong storm during the journey. In my opinion, this ocean is more suitable for the name "Great", which in 1753 was proposed by the French geographer ANDen-Nicholas Buache. However, this name did not take root, and the ocean is still called the Pacific Ocean.

Scientists claim that average depth Pacific Ocean - 3984 m. And the deepest place is in Mariana Trench and its depth is - 10 994 m. Just an incredible number! And I was wondering how you can measure such a depth?

How is ocean depth measured?

It turns out that people have been trying to measure the depth of the ocean for a very long time. Previously, the measurement was done using a rope with a load tied to the end. This load was lowered into the water and, along the length of the rope, a conclusion was drawn about the depth of the bottom in this place.

Later, oceanologists came up with an interesting way to accurately measure the depth of the seas and oceans. This method is called depth listening. It uses a special device to study the ocean floor - echo sounder.

The measurement method is as follows. The device on board the ship sends a sound signal. The sound travels through the water column and, reflected from the bottom, returns and is captured by the echo sounder. Scientists note the time it takes sound to travel to the bottom and back, and so calculate the depth. A modern echo sounder sends ultrasonic waves, which are registered by a special device and plotted on paper.

Studying the ocean floor, scientists came to the conclusion that at different depths the landscape is very different. This, of course, affected the inhabitants of the ocean. Appearance, the diet and behavior of deep-sea individuals are not at all similar to those that live at shallow depths.

Amazing inhabitants of the depths of the Pacific Ocean

When I look at photographs of these creatures, it's hard for me to imagine that they really exist. They look like some kind of fantastical creatures from an adventure novel to me.

These Pacific people impressed me the most:

• acupuncture;
• frilled shark;
• deep sea angler.

Iglorot looks intimidating. Despite its not impressive size, about 15 centimeters, this fish is able to scare anyone away from itself. This creature lives in the deep over 1800 meters where almost no sunlight penetrates. Therefore, the needlemouth itself illuminates its own path, using its bioluminescent organs to illuminate.

frilled shark looks like a prehistoric monster. At one glance, it seems that he fell into the era of dinosaurs. Study her behavior natural environment scientists have not been able to on the surface, this fish dies. What secrets this predator keeps, we can only guess.

It is hard to imagine how many more amazing discoveries we have to make while studying the deepest ocean on the planet.

Found the latest news. On October 1, 2017, a video appeared on the network with two unidentified flying objects. The version that aliens are conducting their research at the bottom of the ocean is a new hit among Internet news. One of the UFOs apparently sank to the bottom of the Pacific Ocean, the deepest in the world. And the second one disappeared. What's under the water?

What is hidden at the bottom of the deepest ocean in the world

Big water hides terrible secrets. I remember from the lessons of history the terrible destruction Japanese islands nuclear weapons. The ill-fated ship USS Indianapolis, on which American sailors brought up components nuclear bomb, in August of this year found at the bottom of the Pacific Ocean.

The ship and crew were left to fend for themselves. More likely, no one was going to save the sailors They might know things that shouldn't be told. So, in the conditions of the wild ocean, sailors died from shark attacks, impotence and disease. In such conditions, three hundred people out of two thousand miraculously survived.

Mysteries of the nature of the ocean

Peering into the depths, you can consider:

• Ostrov, which is not;
• crab migration;
• new types of living beings.

Near Panama at a depth of about 400 meters, an amazing phenomenon was accidentally filmed from a submarine. The crabs were moving in a certain direction, overtaking each other, at a slow pace. They climbed one over the other. What has become the cause of extraordinary behavior is a mystery, which oceanologists are studying today.

At a depth of four hundred thousand meters there is a plain, geographically it can be represented between California and Hawaii. It's very cold at the bottom. But unique living beings unknown to science live on the surface of the water. Some of them cannot be attributed to any family of known organisms.

As a child, I had a book - "The seas and oceans of the planet." In it I read about many amazing places oceans, including the deepest place on our planet.

deepest ocean

Most big ocean the planet is not at all distinguished by a calm "temper". In my time Magellan very lucky to pass its waters without encountering any serious storms, and therefore he named it "Quiet". If we count the entire water surface of our planet as 100%, then it turns out that this ocean accounts for almost 47%. And if we imagine that all the land is one mainland, then all of it will be significantly inferior in area to the great ocean. The deepest place is also within it - Mariana Trench - over 11,000 meters. In addition to the Mariana Trench, there are other deep points where the depth reaches 10,000 meters:

• Kemadek;
• Tonga;

• Philippine Trench.

As for the number of islands, Pacific Ocean- the undisputed leader, within which are scattered over 30,000 islands different sizes.

Features of the great ocean

fire ring. This is the name of the area at the junctions continental plates. Within it is concentrated most of active volcanoes of our planet, and the largest number of tremors is recorded. Why is it of interest to scientists? First of all, actually 95% of all earthquakes that occur recorded here, and most of them are among the strongest in the history of our planet. This is direct evidence that the process formation of continents in this area continues to this day.

Tsunami. These waves, which demolish everything in their path, in fact, " business card» Pacific Ocean. They differ from the usual waves not at all in height, as many believe. It's not exactly a wave, but movement of the entire water column. That is why they go on land, flooding coastal areas. Their number can be from 2 to 30, depending on the power of the earthquake. The ridges go one after another with an interval of up to 2 hours and even more. Therefore, after a tsunami, it is strictly forbidden to go ashore without waiting at least 4 hours. A characteristic sign of an approaching danger is abrupt retreat of the water from the shore, and the further the water goes, the higher the wave will be.

Of the 5 existing oceans in the world, only the Pacific can boast of its size and depth. Its area extends from the Arctic to the Southern Oceans and is 169.2 million km².

It owns almost half (46%) of the world body of water. If we take the entire globe as 100%, then the Pacific Ocean owns 30% of the entire surface on the planet.

What is the deepest ocean? All the same Quiet! And only thanks to the Mariana Trench, which was formed, according to scientists, as a result of the collision of two oceanic plates. The depth of the Mariana Trench is impressive - 11035 meters!

It is noteworthy that the deepest point of the ocean is further sea level than highest point on the planet - Mount Everest above it.

5 water deserts of the world

Much on earth more water than sushi. People have discovered continents and islands, but most of the globe is hidden under water.

Whole Earth covered by the waters of five oceans: Pacific, Atlantic, Indian, Arctic and Southern. The single water element of the oceans changes its properties as latitude changes.

As you can see from the table, the Pacific Ocean is considered the largest and deepest by right. "Abyss of the Challenger" - the most deep point Mariana Trench, its depth is 11035 meters.

The oceanic trench is called the Mariana Trench because of the islands of the same name located around it.

And the smallest ocean is the Arctic Ocean, whose area is 11 times smaller than the Pacific. But it ranks second after the Pacific in terms of the number of islands on it, one of which, Greenland, is the largest in the world.

Great and varied

Previously, the deepest ocean in the world was called the "Great", since it owns 50% of the surface of the world's oceans. It is located north and south of the equator, and it is at the equator that its width is maximum. That's why it's the warmest.

The Pacific Ocean affects almost all climatic zones, so here are different types flora and fauna.

The ocean does not correspond to its name, it is far from quiet. But this is not surprising, they could at one time call Greenland a green country, and Iceland an icy one.

In different parts of it, different winds blow, called trade winds, monsoons, hurricanes constantly sweep over its surface, and storms rage very often in the temperate part of the ocean. Waves reach 30 meters high, and raging typhoons can raise huge pillars of water.

Temperature regime the surface of the water varies greatly, in the north it can drop to -1˚С, and at the equator it can reach +29˚С.

In addition, more precipitation falls over the giant's surface than moisture evaporates, so the water in the ocean is less salty than usual.

Due to its location in many climatic zones, the world of flora and fauna here is very rich and diverse.

The diversity of nature gives rise to the incredible fertility of water masses: in different places researchers found large schools of fish - from salmon to herring. Pacific flotillas are famous for the industrial catch of horse mackerel, mackerel, butterfish, flounder, pollock and other species.

The abundance of fish is an important condition for the life of seabirds. Therefore, penguins, pelicans, cormorants and seagulls will always find something to profit from. There are also famous whales here, which can be recognized from afar by the huge fountains of water on the sea surface. Lots of seals and sea beavers.

Big variety and shellfish, crabs, squids, hedgehogs. The largest mollusk that lives only in the Pacific Ocean, tridacna, weighs about a quarter of a ton. A lot of sharks, huge tunas and sailboats live in it.

The ocean can boast of its mountain range. It was created for millions of years by living organisms and has such a height, only under water, as Ural Range. It is the largest on earth natural complex called Big barrier reef.

A variety of colors, different shades, in which coral colonies are painted, create for diving Magic world, ready to captivate anyone. These are bizarre castles, colorful floral arrangements, and mysterious mushrooms. The diversity of echinoderms, different breeds of crayfish, mollusks, and exotic fish is striking.

Fifty countries are located on the shores of the Pacific Ocean, the number of which is half the population of the Earth.

Which ocean is the deepest and why is the water salty in it - a short description of this issue. The oceans are still a mystery to us. We don't even know their exact age. Perhaps, initially, the Earth's oceans did not exist. Modern man actively studying the ocean floor.

It is already reliably known that up to a mark of 3600 m, the ocean floor is lined with soft silty deposits - calcareous skeletons of the smallest marine animals. Deeper than 6 km, the bottom is covered with fine red silt, it is also called "red clay". It contains the smallest particles of dead animals and small marine plants, volcanic ash.

The depth of the oceans is determined by sending sound waves into the depths and capturing the reflected signal. At the same time, the time it takes for the sound to reach the bottom and back is fixed; then the resulting value is divided in half.

These measurements give us a pretty good idea of ​​the average depth of the oceans and where the depth reaches largest.

Which ocean is the deepest - the deepest ocean on Earth - is the Pacific

(the average depth of which is 4,281 m).

The second place is occupied by the Indian Ocean

(its average depth is 3,963 m).

Atlantic Ocean - in third place

(average depth is 3,926 m).

By the way, for comparison: the depth Baltic Sea is only 55 m!

And the average depth of the Hudson Bay, which is larger than some seas, is only 183 m.

The deepest place in the ocean is near the Guam Islands (Atlantic Ocean) - 10,790 m.

Why is ocean water salty

Sometimes we are faced with questions relating to our planet Earth that have not yet been answered. For example, the presence of salt in the oceans. How did she get there?

We don't know where the salt in the ocean comes from! Of course, salt dissolved in rainwater is known to end up in the oceans. This is an ongoing process.

But this does not explain the huge amount of salt in the oceans. If it were possible to drain all the oceans, a wall 2 km thick could be built from the resulting salt, with a height equal to 230 km. This wall would stretch along the equator across the entire Earth. There is another comparison. The volume of salt dissolved in all oceans exceeds the volume European continent 15 times!

The salt that ends up on our table is mined from salt springs, sea ​​water or mining deposits of rock salt. Sea water contains 3-3.5% salt. But the inland seas - for example, the Black, Red - contain much more salt than the open ones. The Dead Sea (an area of ​​728 sq. km) contains 10,523 million tons of salt.

A liter of sea water contains 30 g of salt. Reserves of rock salt were formed millions of years ago as a result of the evaporation of sea water. Necessary condition salt formation should be the evaporation of nine-tenths of the volume of water. There is an assumption that in places where salt deposits are found, waters once rustled inland seas. Water evaporated much faster than its reserves were replenished. This is how modern deposits of rock salt appeared.

The lion's share of edible salt is extracted from rock salt.

Which ocean is the deepest - and maybe not the Pacific, it is likely that researchers have not yet found deep places in other oceans, devices can also provide erroneous data!
