The Eurasian continent has no clear boundaries within itself.
The location of Europe and Asia was often reviewed, challenged, and changed.
Today, the border between the continents is officially designated, but many scientists do not quite agree with the decision.
The official border between Asia and Europe
The border on the continent is very difficult to conduct. Between Asia and Europe, it constantly changed its outlines. This was due to the gradual development of the Ural mountains and lands of Siberia.
The official division of one continent into two(In the direction North-South) was carried out in 1964. At the 20th Congress of the International Geographical Union, scientists conducted a clear line-border between Asia and Europe. According to these data, the following situation was fixed.
The beginning of the border takes in the Kara Sea, inBaydaratskaya Bay. Further, the division line runs along the eastern part of the Ural Mountains and follows down the east of the Perm region. Thus, both Chelyabinsk and Ekaterinburg turn out to be located in Asia.
Further the border goes along the Ural river, passes intoOrenburg region and descends to the northern part of Kazakhstan. There it is "picked up" by the river Emba and descends straight to the Caspian Sea. Leaving the northern coast of the Caspian Sea in Europe, the border reaches the Kuma River and along with it crosses the northern part of the Caucasus Mountains. Then the way passes through the Don to the Sea of Azov, and then to the Black Sea. From the latter, the border between Asia and Europe "flows" into the Bosporus Strait, where it ends.
Ending in the Bosporus Strait, the border was divided into two continents by Istanbul. As a result, it has two parts: European and Asian (eastern).
On the way of the border there are several states,Which she safely "divides" into two continents. This applies to Russia, Ukraine, Kazakhstan, Turkey. It should be noted that the last "got" the most: the border was divided into two parts by its capital.
Recommendations on the location of borders
However, after the official border,Disputes and arguments about it did not abate. Scientists assure the impossibility of a clear line for any external / internal parameters. For example, on vegetation, climate or soils. The only real measure is the geological history of the area. Therefore, the Urals and the Caucasus turned out to be the main frontier points.
Today, the Caucasus and the Urals are not divided by a border into parts. It passes only at their footsteps, leaving the mountains untouched. This approach greatly simplified the work of geologists.
But this situation was affected by the difficulties in workCartographers. Reproducing one of the continents, scientists had to divide the mountain ranges into unequal parts. It is almost impossible to conduct such a procedure. This situation adversely affected the work of geologists, often using maps: parts of the mountains were "scattered", although historically they were single arrays.
Therefore, today there are some recommendationsAnd arrangements. The Ural mountains can be completely attributed to the European continent. The Caucasian mountains, often, are entirely depicted in the Asian part. The Azov Sea is European.
