The mainland is called a significant surface of sushi, which is washed from all sides by the oceans or by the seas.
How many continents on earth and their name
Earth is a very large planet, but despite this, its significant area is water - more than 70%. And only about 30% occupy the continents and different magnitude of the island.
One of the largest is EurasiaHe takes more than 54 million kvadratric meters. It contains 2 the largest parts of the world - Europe and Asia. Eurasia is the only mainland that is washed from all sides by the oceans. On his shores you can see a large number of large and small bays, different magnitude of the islands. Eurasia is located on 6 tectonic platforms, which is why its relief is so diverse.
The highest mountains are located in Eurasia, as well as Baikal - the deepest lake. The population of this part of the world is almost a third of the entire planet who live in 108 states.
Africa takes over 30 million square meters. The name of all the continents on the planet is studied in detail in the school program, but some people and in adulthood do not know their quantity. This may be due to the fact that in the lessons of geography, the mainland is often called continents. These two names have significant differences. The main difference is that the continent has no border on land.
Africa among all others is the fierce. The main part of its surface is the plains and mountains. In hot Africa, the longest river-Neil on Earth, as well as the desert - sugar flows.
Africa is divided into 5 regions: South, North, Western, Eastern, as well as central. 62 countries are located on this part of the earth.
The name of all continents includes North America. She is washed from all sides by the quiet, north-ice, as well as the Atlantic Ocean. North America's shore is uneven, a large number of large and small bays, different sizes, spills and bays formed along it. In the central part there is a huge plain.
North America
Local residents of the mainland - Eskimos, or the Indians. In total, there are 23 states in this part of the state, among them: Mexico, USA and Canada.
South America occupies On the surface of the planet more than 17 million square meters. It is washed by the quiet and atlantic ocean, and is also the longest mountain system. The rest of the surface is predominantly plateau or plains. Among all parts, South America is the rainy. Her indigenous people are Indians living in 12 states.
South America
In the number of continents on the planet Earth enters and AntarcticaHer area is more than 14 million square meters. The whole surface is covered with ice boulders, the average thickness of this layer is about 1500 meters. Scientists are calculated if this ice is completely melted, the water level on Earth would rise by about 60 meters!
Antarctica
Its main square is a desert from ice, the population lives only on the shores. Antarctica is the lowest surface of the planet, the average air temperature - from -20 to -90 degrees.
Australia - occupied area of \u200b\u200bmore than 7 million square meters. This is the only continent of only 1 state. Plains and mountains occupy its main area, they are located along the entire coast. It is in Australia that lives the largest number of large and small wild animals and birds, here the greatest variety of vegetation. Indigenous people - Aborigines and Bushmen.
Australia
How many continents on Earth 6 or 7?
It is believed that their number is absolutely not 6, but 7. The territory located around the southern pole is huge blocks of ice. Currently, its many scientists call another mainland on the planet Earth. But there is no life on this southern pole, only penguins live.
To the question: " How many continents on the planet Earth?"You can answer exactly - 6.
Continents
On Earth there are only 4 continents:
- America.
- Antarctica.
- Australia.
- Africania.
But in each country there is a view about their quantity. For example, in India, as well as residents of China, they believe that the total number of them is 7, the inhabitants of these countries call Asia and Europe with certain continents. Spaniards, when they mention the continent, call all the surfaces of the light associated with America. And the residents of Greece say that only 5 continents on the planet, because people live on them.
What is the difference between the island from the mainland
And then, and another definition is a large or smaller area of \u200b\u200bland, from all sides washed with water. At the same time, there are certain, significant differences between them.
- Dimensions. One of the smallest is Australia, it takes a much larger area than Greenland - one of the largest islands.
- History of education. Each island is formed in a special way. There are continents that arose as a result of the ancient debris slabs of the lithosphere. Others - turned out due to volcanic eruptions. There are also those species that appeared from polyps, they are called "coral islands".
- His inhabitability. Absolutely all six continents have life, even on the coldest - Antarctica. But most of the islands so far remain uninhabited. But they can meet animals and birds of a wide variety of breeds, to see the plants, still unexplored by a person.
