Now, studying geography in the classroom, we have a lot of information: maps, diagrams, photographs. Back in the 19th century, knowledge about natural areas was very scarce. For a long time, Dokuchaev was engaged in them, but he was never able to systematize the collected data, and his work was continued by L. S. Berg, a well-known geographer in the USSR.
Parameters of characteristics of natural zones
Any biological complex has similar characteristics. This applies to flora and fauna, soil, weather conditions in winter and summer. The student's task is to be able to organize information and provide a description of the natural zones of Russia using a table.
L. S. Berg not only gave a detailed description of the natural zones of all of Eurasia, but also identified the differences on other continents. His textbook "The Nature of the USSR" became the basis for the knowledge that we have now.

Rice. 2. Taiga
The formation of natural zones in mountainous areas occurs at a level of more than 2000 m. In the Caucasus and the Urals, this height corresponds to alpine meadows, in the northern regions of the Siberian mountains - mountain tundra.
