The theory related to the Cycle of Erosion of Penck has the following drawbacks:
1. Penck presented the theory of the Cycle of Erosion in German language. When it was translated from German to other languages (mainly in English), the meaning became distorted.
2. The theory becomes non-interesting due to being obscure.
3. Scholars do not agree on the concept of continuous movement in crust and the parallel withdrawal of slopes as presented by Penck.
