Geographers traditionally divide the vast territory of Russia into five natural zones: the tundra zone; the Taiga, or forest, zone; the steppe, or plains, zone; the arid zone; and the mountain zone. Most of Russia consists of two plains (the East European Plain and the West Siberian Plain), three lowlands (the North Siberian, the Central Yakutian and the East Siberian), two plateaus (the Central Siberian Plateau and the Lena Plateau), and two systems of mountainous areas (the East Siberian Mountains in far northeastern Siberia and the South Siberian Mountains along the southern border).

The East European Plain encompasses most of European Russia. The West Siberian Plain, which is the world's largest, extends east from the Urals to the Yenisei River. Because the terrain and vegetation are relatively uniform in each of the natural zones, Russia presents an illusion of uniformity. Nevertheless, Russian territory contains all the major vegetation zones of the world except a tropical rain forest.

The Russian Arctic stretches for close to 7,000 kilometres (4,300mi) west to east, from Karelia and the Kola Peninsula to Nenetsia, the Gulf of Ob, the Taymyr Peninsula and the Chukchi Peninsula (Kolyma, Anadyr River, Cape Dezhnev). Russian islands and archipelagos in the Arctic Sea include Novaya Zemlya, Severnaya Zemlya, and the New Siberian Islands.

About 10 percent of Russia is tundra[17]a treeless, marshy plain. The tundra is Russia's northernmost zone, stretching from the Finnish border in the west to the Bering Strait in the east, then running south along the Pacific coast to the northern Kamchatka Peninsula. The zone is known for its herds of wild reindeer, for so-called white nights (dusk at midnight, dawn shortly thereafter) in summer, and for days of total darkness in winter. The long, harsh winters and lack of sunshine allow only mosses, lichens, and dwarf willows and shrubs to sprout low above the barren permafrost. Although several powerful Siberian rivers traverse this zone as they flow northward to the Arctic Ocean, partial and intermittent thawing hamper drainage of the numerous lakes, ponds, and swamps of the tundra. Frost weathering is the most important physical process here, gradually shaping a landscape that was severely modified by glaciation in the last ice age. Less than one percent of Russia's population lives in this zone. The fishing and port industries of the northwestern Kola Peninsula and the huge oil and gas fields of northwestern Siberia are the largest employers in the tundra. With a population of 180,000, the industrial frontier city of Norilsk is second in population to Murmansk among Russia's settlements above the Arctic Circle. From here you can also see the auroras (northern lights).

Taiga, the most extensive natural area of Russia, stretches from the western borders of Russia to the Pacific. It occupies the territory of the Eastern Europe and West Siberian plains to the north of N and most of the territory east of Yenisei River taiga forests reach the southern borders of Russia in Siberia taiga only accounts for over 60% of Russia. In the northsouth direction the eastern taiga is divided (east of the Yenisei River), with a continental climate, and west, with a milder climate, in general, the climate zone is moist, moderately warm (cool in the north) in the summer and harsh winter, there is a steady snow cover in the winter. In the latitudinal direction, the taiga is divided into three subzones - northern, middle and southern taiga. In the western taiga dense spruce and fir forests on wetlands alternate with pine forests, shrubs, and meadows on the lighter soils. Such vegetation is typical of the eastern taiga, but it plays an important role not fir and larch. Coniferous forest, however, does not form a continuous array and sparse areas of birch, alder, willow (mainly in river valleys), the wetlands - marshes. Within the taiga are widespread fur-bearing animals - sable, marten, ermine, moose, brown bear, Wolverine, wolf, and muskrat.[18]

In the taiga is dominated by podzolic and cryogenic taiga soils, characterized by clearly defined horizontal structure (only in the southern taiga there is sod-podzolic soil). Formed in a leaching regime and in poor humus. Groundwater is normally found in the forest close to the surface, washing calcium from the upper layers, resulting in the top layer of soil of the taiga being discolored and oxidized. Few areas of the taiga, suitable for farming, are located mainly in the European part of Russia. Large areas are occupied by sphagnum marshes (here is dominated by podzolic-boggy soil). To enrich the soil for agricultural purposes lime and other fertilizers should be used.

Russian Taiga has the world's largest reserves of coniferous wood, but from year to year - as a result of intensive logging - they decrease. Development of hunting, farming (mainly in river valleys).

The mixed and deciduous forest belt is triangular, widest along the western border and narrower towards the Ural Mountains. The main trees are Oak and Spruce, but many other growths of vegetation such as ash, aspen, birch, hornbeam, maple, and pine reside there. Separating the taiga from the wooded steppe is a narrow belt of birch and aspen woodland located east of the Urals as far as the Altay Mountains. Much of the forested zone has been cleared for agriculture, especially in European Russia. Wildlife is more scarce as a result of this, but the roe deer, wolf, fox, and squirrel are very common.

The steppe has long been depicted as the typical Russian landscape. It is a broad band of treeless, grassy plains, interrupted by mountain ranges, extending from Hungary across Ukraine, southern Russia, and Kazakhstan before ending in Manchuria. In a country of extremes, the steppe zone provides the most favorable conditions for human settlement and agriculture because of its moderate temperatures and normally adequate levels of sunshine and moisture. Even here, however, agricultural yields are sometimes adversely affected by unpredictable levels of precipitation and occasional catastrophic droughts. The soil is very dry.

Russia's mountain ranges are located principally along its continental dip (the Ural Mountains), along the southwestern border (the Caucasus), along the border with Mongolia (the eastern and western Sayan Mountains and the western extremity of the Altay Mountains), and in eastern Siberia (a complex system of ranges in the northeastern corner of the country and forming the spine of the Kamchatka Peninsula, and lesser mountains extending along the Sea of Okhotsk and the Sea of Japan). Russia has nine major mountain ranges. In general, the eastern half of the country is much more mountainous than the western half, the interior of which is dominated by low plains. The traditional dividing line between the east and the west is the Yenisei River valley. In delineating the western edge of the Central Siberian Plateau from the West Siberian Plain, the Yenisey runs from near the Mongolian border northward into the Arctic Ocean west of the Taymyr Peninsula.

The Ural Mountains form the natural boundary between Europe and Asia; the range extends about 2,100 kilometres (1,300mi) from the Arctic Ocean to the northern border of Kazakhstan. Several low passes provide major transportation routes through the Urals eastward from Europe. The highest peak, Mount Narodnaya, is 1,894 metres (6,214ft). The Urals also contain valuable deposits of minerals.

To the east of the Urals is the West Siberian Plain, stretching about 1,900 kilometers from west to east and about 2,400 kilometers from north to south. With more than half its territory below 200 meters in elevation, the plain contains some of the world's largest swamps and floodplains. The plain is largely flat and featureless. The only slightly elevated areas are the Siberian Uvaly across the central part and the Ob Plateau in the south.[19] There are steppe areas in the southern part reaching into Kazakhstan, such as the Ishim Steppe with the Kamyshlov Log trench. Most of the plain's population lives in the drier section south of 77 north latitude.

The region directly east of the West Siberian Plain is the Central Siberian Plateau, which extends eastward from the Yenisei River valley to the Lena River valley. The region is divided into several plateaus, with elevations ranging between 320 and 740 meters; the highest elevation is about 1,800 meters, in the northern Putoran Mountains. The plain is bounded on the south by the Primorsky Range and the Baikal Mountains, and on the north by the North Siberian Lowland, an extension of the West Siberian Plain extending into the Taymyr Peninsula on the Arctic Ocean.

In the mountain system west of Lake Baikal in south-central Siberia, the highest elevations are 3,300 meters in the Western Sayan, 3,200 meters in the Eastern Sayan, and 4,500 meters at Belukha Mountain in the Altay Mountains. The Eastern Sayan reach nearly to the southern shore of Lake Baikal; at the lake, there is an elevation difference of more than 4,500 meters between the nearest mountain, 2,840 meters high, and the deepest part of the lake, which is 1,700 meters below sea level. The mountain systems east of Lake Baikal are lower, forming a complex of minor ranges and valleys that reaches from the lake to the Pacific coast. The maximum height of the Stanovoy Range, which runs west to east from northern Lake Baikal to the Sea of Okhotsk, is 2,550 meters. To the south of that range is southeastern Siberia, whose mountains reach 800 meters. Across the Strait of Tartary from that region is Sakhalin Island, Russia's largest island, where the highest elevation is about 1,700 meters. The small Moneron Island, the site of the shootdown of Korean Air Lines Flight 007, is found to its west.

Truly alpine terrain appears in the southern mountain ranges. Between the Black and Caspian seas, the Caucasus Mountains rise to impressive heights, forming a boundary between Europe and Asia. One of the peaks, Mount Elbrus, is the highest point in Europe, at 5,642 meters. The geological structure of the Caucasus extends to the northwest as the Crimean and Carpathian Mountains and southeastward into Central Asia as the Tian Shan and Pamirs. The Caucasus Mountains create an imposing natural barrier between Russia and its neighbors to the southwest, Georgia and Azerbaijan.

Northeastern Siberia, north of the Stanovoy Range, is an extremely mountainous region. The long Kamchatka Peninsula, which juts southward into the Sea of Okhotsk, includes many volcanic peaks, some of which are still active. The highest is the 4,750-meter Klyuchevskaya Sopka, the highest point in the Russian Far East. The volcanic chain continues from the southern tip of Kamchatka southward through the Kuril Islands chain and into Japan. Kamchatka also is one of Russia's two centers of seismic activity (the other is the Caucasus). In 1995, a major earthquake largely destroyed the oil-processing town of Neftegorsk. Also located in this region is the very large Beyenchime-Salaatin crater.

Russia, home to over 100,000 rivers,[1] is divided into twenty watershed districts. It has one of the world's largest surface water resources, with its lakes containing approximately one-quarter of the world's liquid fresh water.[20] Russia is second only to Brazil by total renewable water resources.[21]

Forty of Russia's rivers longer than 1,000 kilometers are east of the Ural Mountains, including the three major rivers that drain Siberia as they flow northward to the Arctic Ocean: the Irtysh-Ob system (totaling 5,380 kilometers), the Yenisey (5,075 kilometers), and the Lena (4,294 kilometers), they are among the world's longest rivers.[22] The basins of those river systems cover about eight million square kilometers, discharging nearly 50,000 cubic meters of water per second into the Arctic Ocean. The northward flow of these rivers means that source areas thaw before the areas downstream, creating vast swamps such as the 48,000-square-kilometer Vasyugan Swamp in the center of the West Siberian Plain. The same is true of other river systems, including the Pechora and the Northern Dvina in western Russia, and the Kolyma and the Indigirka in Siberia. Approximately 10 percent of Russian territory is classified as swampland.

Russia's inland bodies of water are chiefly a legacy of extensive glaciation. Ladoga and Onega in northwestern Russia are two of the largest lakes in Europe.[1] However, Lake Baikal is the largest and most prominent among Russia's fresh water bodies, is the world's deepest, purest, oldest and most capacious fresh water lake, containing over one-fifth of the world's fresh surface water.[23] Numerous smaller lakes dot northern Russia and Siberian plains. The largest of these are lakes Belozero, Topozero, Vygozero, and Ilmen in the country's northwest and Lake Chany in southwestern Siberia.

A number of other rivers drain Siberia from eastern mountain ranges into the Pacific Ocean. The Amur River and its main tributary, the Ussuri, form a long stretch of the winding boundary between Russia and China. The Amur system drains most of southeastern Siberia. Three basins drain European Russia. The Dnieper, which flows mainly through Belarus and Ukraine, has its headwaters in the hills west of Moscow. The 1,860-kilometer Don, which is the fifth-longest river in Europe, originates in the Central Russian Upland south of Moscow and then flows into the Sea of Azov at Rostov-on-Don. The Volga, widely seen as Russia's national river due to its historical and cultural importance, is the longest river in Europe,[22] it rises in the Valdai Hills west of Moscow and meandering southeastward for 3,510 kilometers before emptying into the Caspian Sea. Altogether, the Volga system drains about 1.4 million square kilometers. Linked by several canals, western Russia's rivers long have been a vital transportation system; the Volga remains the country's most commercial river, and carries about two-thirds of Russia's inland water traffic.
