Which geographic region of russia was especially suitable for nomadic invaders and why? 1.the ural mountains because they contain higher ground 2.the southern steppe because it is an open, treeless grassland 3.the central farmland because it contains vast fields of wheat

The geographic region of Russia that was especially suitable for nomadic invaders is the southern steppe because it is an open, treeless grassland. Thus, there was no geographical border that prevented the invaders from marching to Russia with their military force. The Ural mountains, on the other hand, gave much protection to Russia against invaders as it prevented access to the region.
