Origin o the Warsaw-Berlin Pradolina

pradolina was blocked. At that time erosion and denudation became morę vioorous. Thouah the destructive processes greatly affected the relief of this area, they were not principal aaents of morphological changes. Increase in their activity was determined by tectonics.

The adjustment of the present-day relief to the morphology of the sub-Quaternary surface indicates that the viqorous upward movements of bedrock which datę back to the last glaciation are still active.
