- semi-closed seas, that is, separated from the ocean by a continent,
- inland seas, located, as a rule, far inland and connected with the oceans by one or two straits,
- marginal seas, located on the edge of land near the ocean,
- interisland seas separated from each other by islands.
In fact, there are quite a large number of seas on planet Earth, and this moment There is no exact figure for time, this is due to the fact that all seas are divided into unique categories, namely:
But as for the oceans, there are five of them on our planet, these are:
1) The Pacific Ocean, which is the largest
2) Southern Ocean
3) Atlantic Ocean
4) Indian Ocean
5) Arctic Ocean
Everyone knows that there are 5 oceans on planet Earth. Pacific Ocean (the largest), Atlantic Ocean, Indian Ocean, Arctic Ocean, Southern Ocean. But it would take a very long time to list all the seas because there are 81 of them.
More and more often they began to say that there are not 4 oceans on Earth, but 5 - the Southern Ocean was added to all the known four, but regarding the seas, according to different sources you can notice that they range in number from 40 to 100, since the concept of sea can be interpreted in different ways, but still the most correct answer would be 81, most of which (as many as 29) belong to the Pacific Ocean, which, of course, is not marvelous.
As for the oceans, everything here is quite transparent. There are only 5 oceans on the planet - the Pacific, Southern, Indian, Atlantic and Arctic. As for the seas, here everything is much more complicated. No one can give an exact answer to this question now. Their number on earth varies from 50 to 100. In order to somehow answer this question, I will give a link where the seas are divided into oceans:
How many seas are there on Earth?
Only the seas belonging to the Southern Ocean are not there yet, because its boundaries were determined only 13 years ago. But still, most people who study this issue tend to claim that there are about 80 seas on Earth.
There are 5 oceans on Earth:
Pacific, Atlantic, Indian, Arctic and Southern (more recently, it seems since 2001, its borders are defined at 60 parallels of southern latitude).
As well as 53 seas and 9 large bays, which in some sources are considered seas.
There are a lot of seas on our Earth, but at the moment there are five oceans - the Pacific, Indian, Southern, Atlantic and Arctic. And there are only about eighty seas; it is difficult to name the exact number, since many scientists cannot determine whether many seas are exactly seas by definition.
As far as I know, there are currently 63 seas on our planet, which does not include the Caspian Sea, the Aral Sea, the Dead Sea, and the Sea of Galilee. In addition, now all these 63 seas are included in the water basins of five oceans, namely the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Arctic Ocean, and the Southern Ocean.
There are only 4 oceans - the Pacific, Atlantic, Indian and Arctic. This division is conditional, since there are no clear boundaries between the oceans.
In total, 59 are called seas water pools pestilent ocean.
The Pacific Ocean basin includes 18 seas and the Gulf of Alaska. The largest of them are Philippine and Coral.
The Atlantic Ocean includes 9 seas and 4 more bays. The largest by area (in descending order): Sargasso Sea, Wedell Sea, Caribbean Sea.
The Indian Ocean includes 6 seas and 3 more bays. The Arabian Sea is considered the largest, with an area of about 4.6 million square kilometers.
The Arctic Ocean includes 10 seas plus Hudson Bay. The Barents Sea is the largest sea that is part of the Arctic Ocean.
The Philippine Sea is considered the largest sea on planet Earth.
There are only five oceans on our planet, namely the Atlantic Ocean, the Pacific Ocean, the Arctic Ocean, the Southern Ocean and the last Indian Ocean. But as we know, scientists cannot determine the exact number of seas.
There are a total of 5 oceans on our planet - the Atlantic, Pacific, Indian, Arctic, Indian and so far unofficially - the Southern, which includes the waters of the Pacific, Atlantic and Indian Oceans and which wash Antarctica.
But as for the seas, it is very difficult to count them, even if you have a world map at hand. But if you look at this list (a little lower), then it is much easier to count them and even if you wish (if you enter the name on the Internet) you can find each sea separately on the map.
List of all the seas of the world in alphabetical order:
I personally counted this list several times and counted 80 seas.
What are the names of the seas of our planet and where are they located:
Below Full description seas with the name and table of the most large seas in area and depth.
All about the seas of our planet:
According to the degree of isolation and characteristics of the hydrological regime, the seas are divided into 3 groups: internal seas (Mediterranean seas and semi-enclosed seas), marginal seas and interisland seas. By geographical location Mediterranean seas are sometimes divided into intercontinental seas and inland seas.
From a geological point of view, modern seas are young formations. In outlines close to modern ones, they were all determined in the Paleogene-Neogene time, and finally took shape in the Anthropocene. The deepest seas (for example, the Mediterranean Sea) are formed in places of large faults in the earth's crust, and shallow seas arose when the marginal parts of continents were flooded by the waters of the World Ocean and are usually located on continental shallows
Classification by ocean
The division of the World Ocean into separate oceans was carried out by the International Hydrological Organization (IHO) in 1953 (with subsequent changes)
There are 63 seas in the world (not counting the Caspian, Aral, as well as the Dead and Galilee seas) - of which 25 are in the Pacific, 16 in the Atlantic, 11 in the Indian and 11 in the Arctic Ocean. Traditionally, due to their large size, seas include the Caspian and Aral seas-lake, which are the remnants of the ancient Tethys ocean. In addition, the names of the Dead Sea and the Sea of Galilee have historically developed.
There are different classifications of seas.

Classification by degree of isolation from the ocean
Seas are distinguished according to the degree of isolation internal, peripheral, intercontinental and interisland.
Inland seas- seas, mostly closed from communication with the ocean, which have limited (compared to marginal seas) water exchange with the World Ocean. In such seas, the depth of the strait connecting them to the ocean is small, which limits deep-sea currents that lead to the mixing of deep waters. Examples of such seas are the Mediterranean and Baltic seas.
Depending on the number of continents whose seashores wash, inland seas are divided into intercontinental(Mediterranean and Red Seas) and inland(Yellow and Black Seas).
Depending on the connection with other seas or the World Ocean, inland seas are divided into isolated(closed) (Dead Sea, Aral Sea) and semi-insulated(semi-closed) (Baltic, Sea of Azov). In fact, isolated seas are lakes.
marginal seas- these are seas that are characterized by free communication with the ocean and, in some cases, separated from them by a chain of islands or peninsulas. Although the marginal seas lie on the shelf, the nature of bottom sediments, climatic and hydrological regimes, the fauna and flora of these seas are strongly influenced not only by the continent, but also by the ocean. Marginal seas are characterized by ocean currents that arise due to oceanic winds. Seas of this type include, for example, the Bering, Okhotsk, Japanese, East China, South China, and Caribbean seas.
Intercontinental seas(sometimes called Mediterranean seas) are seas that are surrounded on all sides by land and connected to the ocean by one or more straits. These seas include the Mediterranean, Red, and Caribbean.
Interisland seas- seas surrounded by a more or less dense ring of islands, the rise of the relief between which prevents the free exchange of water between these seas and the open part of the ocean.
Most of the interisland seas are found among the islands of the Malay Archipelago. The largest of them: Javanese, Banda, Sulawesi.
Classification by surface water temperature
There is also a classification of seas depending on the temperature of their surface waters (tropical seas, temperate zone seas, polar seas), but it is practically not used.
Classification by water salinity
According to the degree of salinity they distinguish highly salted And lightly salted seas.
Highly salty seas- seas that have a higher salinity than in the ocean due to active evaporation, and their water exchange consists of the outflow of more saline sea water into the lower layers, and the influx of more fresh water into the surface layers through straits from the ocean. An example of such a sea is the Red Sea.
Lightly salted seas- seas that have less salinity than the ocean due to the fact that the influx of fresh water with river runoff and precipitation is not compensated by evaporation. In this case, water exchange consists of the outflow of less saline sea water into the surface layers and the influx of more saline water into the bottom layers through the straits. In such basins, water exchange with the bottom layers is often insufficient to maintain the majority of biological species oxygen content. An example of such a sea is the Black Sea.
Classification by coastline ruggedness
Distinguish strongly rugged and weakly rugged coastline. It should be noted that, for example, the Sargasso Sea has no coastline at all.
Coastline
The coastline of the seas is characterized by the presence of bays, lagoons, coves, estuaries of flowing rivers, peninsulas, spits, estuaries, beaches or cliffs and other forms of relief.
Bay- this is a part of the sea that extends deeply into the land, but has free water exchange with the main part of the sea. The hydrological and hydrochemical conditions of the bay are identical to the conditions of the sea of which they are part. IN in some cases Local climate features and continental runoff can give the hydrological characteristics of the surface layer of bays some specific features.
Depending on the coastal topography and other geographical conditions, bays are divided into several types:
· Bay- a small part of the sea, separated from open waters on three sides by parts of land (shore protrusions, rocks and nearby islands) and protected by them from waves and wind. Most small bays are formed in soft rocky soils or clays washed out by waves. Examples of bays are Sevastopol and Balaklava bays in the Black Sea, Zolotoy Rog Bay in the Sea of Japan. A small bay can be part of a larger bay, such as the Yuzhnaya Bay as part of the Sevastopol Bay.
· Liman- a bay delimited from the sea by a sand spit (bar). More often, an estuary is a flooded part of the section of a river valley closest to the sea (for example, the Dnieper and Dniester estuaries on the Black Sea coast). Distinguish open estuaries(estuarine type) - having constant water exchange with the sea, and closed type(lagoon type) - separated from the sea by a sand spit or bar. The hydrological regime of the estuary is largely influenced by the river that flows into it.
· Lagoon- a shallow part of the sea, separated from it by a bar, spit, or coral reef and often connected to it by a narrow strait. Lagoons differ from other bays in their greater degree of isolation from the sea. Often found inside the atoll (for example, Kiritimati, Kwajalein atolls).
· Estuary- a single-arm, funnel-shaped mouth of a river that flows into the sea. An estuary is formed when the sea floods the mouth of a river, and tidal forces carry sediment out to sea and prevent the estuary from filling up and turning into a delta. This happens when the part of the sea adjacent to the estuary has great depth. The estuary is formed by rivers such as the Amazon (Atlantic Ocean) and Thames (North Sea).
· Fjord- a long, narrow sea bay, often extending far inland. The fjord is formed as a result of the flooding of the former glacier valley by the sea. Many fjords are very deep - they were formed when glaciers crushed valleys with their weight, and then the valleys were flooded by the sea. Typically, the length of a fjord is several times greater than its width. Examples of typical fjords are the fjords of the Norwegian Sea.
· Lip- a common name in northern Russia for a bay that cuts deeply into the land (for example, Nevskaya in the Gulf of Finland, Ob in the Kara Sea).
Strait- a relatively narrow strip of water separating land areas and connecting adjacent water basins or parts thereof (for example, the English Channel, Magellan, Bering Straits).
Island- a piece of land (often of natural origin), surrounded on all sides by water and constantly rising above the water even during the highest tide (for example, Greenland, Madagascar). They differ from continents in their small size, for example Greenland is three times smaller than the smallest continent of Australia ( islands-mainland). They vary in origin, shape and type (for example, coral island).
· Atoll- is a rise on the ocean floor, usually conical in shape, formed by an extinct volcano, crowned with a coral superstructure that forms a reef with a group of islets (motu), separated by straits that connect the ocean with the lagoon. If there are no straits, then the land is closed in a continuous ring, and the water in the lagoon may differ in composition from the surrounding ocean.
· Archipelago- a group of closely located islands having a similar geological structure.
· Skerries- (from Nor. sker - rock in the sea) - an archipelago consisting of small rocky islands, separated by narrow straits and covering a significant part of the coastal sea strip, bordering fjord-type shores. Each of these islands is individually called " skerry" As a rule, skerries are suitable for navigation, but the passage of ships in them requires certain skills and is fraught with many dangers. During the Great Patriotic War torpedo boats of the Baltic Fleet successfully fought against the invaders, using skerries for cover.
· artificial island- a separate group of islands created by man (for example, Kansai Airport in the middle of Osaka Bay in Japan and the elite Palm Jumeirah beach, created off the coast of Dubai in the United Arab Emirates).
Scythe- a low alluvial strip of land on the shore of a sea or lake, connected at one end to the shore. It is formed as a result of the movement of debris along the coast by waves. It is composed of sediment (sediment) of bulk materials moved by currents: sand, pebbles, gravel, shells. The spit, formed as a result of the simultaneous entry of sediment from both sides, protrudes into the open sea almost perpendicular to the shore and is called arrow. Can be created artificially.
Cape- a piece of land that cuts into the sea. Can be formed by either sediment or sediment. Capes, as a rule, owe their existence to erosion processes. A prerequisite for the appearance of a cape is the presence of both soft and hard rocks on the coastline. Soft rocks, such as sand, are destroyed by waves much faster than hard rocks. As a result, a cape is formed (for example, Horn, Good Hope).
Peninsula- a part of the continent that protrudes far into the sea and is washed on three sides by water and is often geologically integral with the mainland (for example, the Iberian Peninsula or the Scandinavian Peninsula).
Mainland- a large area of land, often washed on all sides by seas or oceans (for example, Eurasia is separated from Africa by the Suez Canal, and the two Americas are separated by the Panama Canal).
How many oceans are there on Earth? I think even fifth-graders will immediately answer: four - and list: Atlantic, Indian, Pacific and Arctic. All?
But it turns out that the four oceans are already outdated information. Today scientists are adding a fifth to them - the Southern, or Antarctic, Ocean.
Browse the wonderful and good article:
However, the number of oceans and especially their boundaries are still a matter of debate. In 1845, the London Geographical Society decided to count five oceans on Earth: Atlantic, Arctic, Indian, Quiet, Northern And Southern, or Antarctic. This division was confirmed by the International Hydrographic Office. But even later for a long time some scientists continued to believe that there were only four “real” oceans on Earth: Atlantic, Pacific, Indian and Northern, or Arctic Ocean. (In 1935, the Soviet government approved the traditional Russian name - .)
So how many oceans are there really on our planet? The answer may be unexpected: on Earth there is a single World Ocean, which people, for their convenience (primarily navigation), have divided into parts. Who will confidently draw the line where the waves of one ocean end and the waves of another begin?..
We found out what oceans are. What do we call seas and how many of them are there on Earth?? After all, the first acquaintances with the water element began on the shores of the seas.
Experts call seas “parts of the World Ocean that are separated from the open ocean by mountains or simply land.” At the same time, marine regions, as a rule, differ from the oceans in meteorological conditions, that is, weather, and even climate. Oceanologists distinguish between internal seas, closed by land, and external seas, as parts of the open ocean. There are seas without shores at all, just stretches of ocean. For example, the waters between the islands.
How many seas are there on Earth? Ancient geographers believed that there were only seven seas-oceans in the world. Today, the International Hydrographic Office lists 54 seas on Earth. But this figure is not very accurate, because some seas not only do not have shores, but are also located inside other water basins, and their names remained either due to historical habit or for the convenience of navigation.
Ancient civilizations developed along the banks of rivers, and rivers (I mean large water streams) flow into seas and oceans. So from the very beginning people had to become familiar with the water element. Moreover, each great civilization of the past had its own sea. The Chinese have their own (later it turned out that this is part of). The ancient Egyptians, Greeks, and Romans had their own - the Mediterranean Sea. The Indians and Arabs have the shores of the Indian Ocean, the waters of which each people called in their own way. There were other centers of civilizations and other main seas in the world.
In ancient times, people did not know much about the world around them and therefore they attributed special mystical meanings to many unknown things. So back in those days, when even great thinkers did not know and did not exist geographical maps world, they believed that there were seven seas on Earth. The number seven, according to the ancestors, was sacred. The ancient Egyptians had 7 planets in the sky. 7 days of the week, 7 years - cycle of calendar years. Among the Greeks, the number 7 was dedicated to Apollo: on the seventh day before the new moon, a sacrifice was made to him.
According to the Bible, the world was created by God in 7 days. Pharaoh dreamed of 7 fat and 7 skinny cows. Seven is found as the number of evil (7 devils). In the Middle Ages, many nations knew the story of the seven wise men.
IN Ancient world There were seven wonders of the world: Egyptian pyramids, the hanging gardens of the Babylonian queen Semiramis, the lighthouse in Atexandria (III century BC), the Colossus of Rhodes, the statue of Olympian Zeus created by the great sculptor Phidias, the Ephesian temple of the goddess Artemis and the mausoleum in Hapicarnassus.
How could one manage without the sacred number in geography: were there seven hills, seven lakes, seven islands and seven seas?
We won't list everything. As a European resident (and I live in the city of St. Petersburg), I will only tell you about the main historical sea European civilization - .
How many seas are there in the world? This question always arouses keen interest among schoolchildren. The world's oceans are considered to be water shell which surrounds the mainland as well as the islands. Some water areas separated by land or elevated underwater terrain are conventionally called seas. It is not easy to say exactly how many seas there are in the world, since there are many different classifications. Total water bodies may vary: for example, the Aral, Dead, Caspian and Galilee seas are usually called seas, although in fact they should be classified as “Lakes”. There are also a number of bays that would be more logical to be classified as seas.
The Atlantic includes the Baltic, North, Sargasso, Marmara, Ionian, Aegean, Adriatic and many other seas. There are about thirty of them in total.
The Indian Ocean includes only six of them, the Red Ocean.
Subdues the thirteen seas. Among them are Beloe, Barents, Chukotka, Kara, East Siberian.
Not all scientists recognize the South as an ocean. However, it contains areas of water that surround Antarctica.
To tell how many seas there are in the world, you can use the latest data from the International Geographical Bureau. Today there are fifty-four of them. Inland seas and bays were not taken into account.
Mediterranean
Leading scientists and international environmental organizations believe that the world today is Mediterranean. The UN also made this conclusion at its recent annual report. Every year, about 100,000 various reasons about five thousand tons of petroleum products. Of particular danger to flora and fauna are the numerous plastic wastes that litter coastal areas.
Baltic
The sad glory of the Mediterranean water element is also shared by the Black and Baltic seas. The most problematic area is considered to be the Baltic Gulf of Finland, which is filled with spilled oil products. Due to the fact that the Baltic Sea is surrounded on all sides economically the developed countries(Sweden, Norway), they dump a significant amount of industrial waste into its waters. Multi-ton waste from the industrial activities of European countries also flows into the Black Sea waters through the flowing rivers.
Marble
The most dangerous sea in the world is Marmara. It is also the smallest. It serves as the border between Europe and Asia and is a connecting link between the Black and Aegean Seas. Many centuries ago, a fault formed in the earth's crust, which was subsequently filled with water. Thus arose the depth of which in some places reaches more than one thousand three hundred meters.
There are numerous dangers in this area of water. natural disasters: tsunamis and earthquakes. For the whole famous story During the existence of the sea, its waters shook about three hundred times.
In the classification of the world's water bodies, there is also an approach in which the seas are divided into categories according to the degree of salinity of the water. The world's oceans are filled with various salts that entered it from previously eroded rocks. The total content of solids dissolved in one kilogram of water is commonly called salinity. Its level is expressed in ppm (tenths of a percent).
Red
Mira - Dead and Red. One liter of Red Sea water contains forty grams of salt. Thanks to the constant mixing of water layers among themselves, the Red Sea has the same temperature and salinity level in any part of it.
At the end of the last century, researchers discovered over two dozen depressions containing hot “brines.” average temperature they are forty degrees. This water is very beneficial for health.
Dead
The Dead Sea is famous for the unique composition of its water and healing mud. Large degree salinity creates a high liquid density.
When talking about the seas, we must cover the entire hydrosphere as a whole, because water is something without which life on Earth is not only impossible, it would not even have arisen on our planet.
Where did the water come from?
Scientists have not yet come to a clear conclusion as to where water came from on Earth. But the most popular and realistic hypothesis today is that an asteroid made entirely of ice once fell to Earth. This version looks quite scientific, since in the distant past our planet was repeatedly hit by meteorites and asteroids. It is likely that some of them contained water in the form of ice or snow-like substance.
Another group of scientists believes that at first the Earth itself was like a cold meteorite. As the ice melted, seas and oceans began to appear as a result of increased solar activity and changes in the tilt of the earth's axis. And since the Sun heats the planet unevenly, it began in nature.
But there are also those who believe that the Earth, on the contrary, was at first like a hot ball. Then, as the planet's surface began to cool, water came out from under the mantle like sweat. But all these theories still do not answer the question of how many seas there are on Earth.
Our planet is unique. It has the largest mass of all its kind, in addition, it is the only one known to man planets that have life. It was formed more than 5 billion years ago, attracting the moon, which became its first and only satellite. The seas depend on the lunar cycle. This dependence is visible in the example
When asked how many seas there are on Earth, textbooks write numbers from 76 to 83. There is even evidence that there are only 49, or even 100. If you think about it, that’s a lot. But in comparison with the total amount of water on Earth, even with the amount of land - both 76 and 83 seas - it is negligible. The difference in numbers is because everyone interprets this concept differently. Some people consider only the coastal part of the ocean to be seas. But in this case, what to do with the inland seas? And with the inter-island ones everything becomes completely unclear. In addition, many seas are now called bays. The reservoir is called this way not by hydrogeographic distinction, but by tradition. For example, everyone knows about the Caspian Sea, although this huge lake with salty bitter water is not a sea.
What types of seas are divided into?
- Interisland. They are often not considered total number seas, because they are located between islands, and not in coastal zone ocean. These include Javanese and New Guinea.
How many seas are there on the planet that are called open? Not so much. These include Sargasso, Ionian, Tyrrhenian.
Has everything been taken into account?
This classification, of course, helps to systematize the expanses of water, but it complicates the answer to the question of how many seas there are on planet Earth. Scientists do not always agree with this division. As a result, either marginal or open seas, which, in fact, have no shores, are beyond the attention of researchers. The most famous is the Sargasso Sea, which consists entirely of algae.
Garbage seas
IN currently, in connection with the general deterioration of the ecology of the planet, the question: “How many seas are there on Earth?” requires drastic revision. For example, scientists identify three more, although they consist not of water, but of garbage. So, in Indian and Pacific Ocean Entire floating continents made of plastic and polyethylene roam. Decomposing under the influence of the sun and water, all this floating garbage releases products into the waters of the world's oceans chemical reactions plastic.
They are disappearing!
But another problem is the disappearance water resources. For example, the once huge Aral Lake has practically disappeared due to economic activity person. Due to the large intake of water from donor rivers, the Aral Lake stopped flowing. As a result, the fauna that inhabited this sea-lake almost completely disappeared.
All of the above shows that the answer to the question of how many seas there are on Earth has yet to be given.
