<P> When large amounts of sediment are deposited on a particular region , the immense weight of the new sediment may cause the crust below to sink . Similarly , when large amounts of material are eroded away from a region , the land may rise to compensate . Therefore , as a mountain range is eroded , the ( reduced ) range rebounds upwards ( to a certain extent ) to be eroded further . Some of the rock strata now visible at the ground surface may have spent much of their history at great depths below the surface buried under other strata , to be eventually exposed as those other strata eroded away and the lower layers rebounded upwards . </P>
