Penck’s Cycle of Erosion

Walther Penck was a German geo-scientist born in 1888 and died in 1923. He worked on geomorphology and landscape very deeply in the German language. His sudden death left his work uncompleted. He pointed out flaws in the Davis Theory of Erosion.

  1. According to Penck, the processes of upheaval and erosion go side by side.
  2. The rate of upheaval is slow and continuous for a long time.
  3. The landscape is the result of the processes of erosion and upheaval.
  4. The cycle of erosion starts on an uplifted dome.
  5. The cycle comprises five stages. The relief increases in the first stage but after a period of stability (2nd to 4th stage), its reduction takes place in the last stage.

Five Stages of Walther Penck’s Theory of Erosion: This part will be composed soon. 

Criticism of Penck’s theory of Erosion:

  1. Penck’s assumptions are based on geology thus these are outdated and backward.
  2. The description of stages of erosion in a sequence does not comply with the facts.
  3. All data of Penck’s cycle looks imaginary because our knowledge in geography is still very limited.
  4. However, Penck’s cycle is impressive due to its logical way of presentation.
  5. Penck has derived the relationship between upheaval and erosion by establishing that erosion starts with the emergence of the landmass.
  6. Penck’s work can not be fully comprehended due to his incomplete work because of his death.
  7. His obscure composition is in difficult old German language, which was not accurately interpreted.
  8. His ill-defined terminologies, some contradictory ideas, and misleading review made by W.M. Davis made his work unsuccessful.
