A cycle of films about physical and geographical countries. So scientists call dissimilar territories that were formed during the geological history of the Earth. There are thirteen of them in Russia. Each has its own geological structure, relief features, and hence the special natural conditions that determine its originality.
To the south of the Russian Plain is the mountainous country of the Caucasus. It stretches for more than a thousand kilometers between the Black and Caspian Seas. The Caucasus Mountains are young, formed about twenty-five million years ago. The Caucasus is characterized by sharp silhouettes with sharp peaks. Earthquakes and landslides are frequent here, as a result of which local landscapes are constantly changing: rivers are blocked, lakes with the purest glacial water are formed. Such as the Bodukskie in the Teberdinsky Reserve.
The most elevated is the central part of the Greater Caucasus. Here is the highest peak in Europe - Elbrus. The Caucasus is the largest mountain glaciation center in Russia. The total area of ​​glaciers is about two thousand square kilometers. Changing their size is one of the indicators of global climate change.
