Answer
The theory of plate tectonics explains the existence of the Ural Mountains in the interior of an expansive landmass through the process of continent-continent collision. The Ural Mountains were formed during the collision between the Siberian and Baltica plates. These two ancient continents collided during the Paleozoic era, specifically during the late Carboniferous to early Permian periods. As a result of this collision, the two continental plates crumpled and folded, leading to the uplift of the Ural Mountains. The compressional forces generated during the collision caused the crust to thicken, resulting in the formation of this north-south-oriented mountain belt in the interior of Eurasia.
