Европейская равнина
The East European Plain (also called the Russian Plain, predominantly by Russian scientists, or historically the Sarmatic Plain) is a vast interior plain extending east of the North European Plain, and comprising several plateaus stretching roughly from 25 degrees longitude eastward. It includes the westernmost Volhynian-Podolian Upland, the Central Russian Upland, and on the eastern border, encompasses the Volga Upland. The plain includes also a series of major river basins such as the Dnepr Basin, the Oka–Don Lowland, and the Volga Basin. Along the southernmost point of the East European Plain are the Caucasus and Crimean mountain ranges. Together with the North European Plain (covering much of north-western France, Netherlands, Germany to north-eastern Poland), and covering the Baltics (Estonia, Latvia and Lithuania), Moldova, south-eastern Romania, and its most southern expansion – the Danubian Plain in Northern Bulgaria, (including Ludogorie and Southern Dobruja), it constitutes the majority of the Great European Plain (European Plain), the greatest mountain-free part of the European landscape.
