DIFFERENCE BETWEEN DAVIS AND PENCK CYCLE OF EROSION

Difference Between the Davis and Penck Cycles of Erosion

• William Morris Davis explained the geographic cycle model in 1899, and it is known as the Davis cycle of erosion.
• The geographic cycle model that Walter Penck explained in 1924 is the Penck cycle of erosion, in contrast.
• The key difference between the Davis and Penck cycles of erosion is that the Davis cycle of erosion is time-dependent and monocyclic, while the Penck cycle of erosion is not time-dependent and is polycyclic.
• Moreover, there are three factors in the Davis cycle of erosion: structure, process, and stages, while there are five factors in the Penck cycle of erosion: primarumpf, aufsteigende, gleichforminge, absteigende, and endrumpf.
• In addition, the Davis cycle of erosion begins only after uplift is stopped.
• In contrast, according to the Penck cycle of erosion, erosion does not remain suspended until the uplift is complete.

Summary

Davis vs. Penck Cycle of Erosion

IMAGE SOURCE 

• The Davis cycle of erosion and the Penck cycle of erosion are two geographic cycle models.
• According to the Davis cycle of erosion, landform formation occurs as a result of three factors: structure, process, and time.
• The Penck cycle of erosion states that there are five causes that cause erosion: primarumpf, aufsteigende, gleichforminge, absteigende, and endrumpf.
• The Davis cycle of erosion also changes over time and only happens once.

IMAGE SOURCE 

• The Penck cycle of erosion, on the other hand, doesn't depend on time and has many cycles.
• The distinction between the Davis and Penck cycles of erosion has been clearly described herein.
