Question

Why does rejuvenation occur in cycle of erosion?

Answer 1

The geographic cycle or cycle of erosion is an idealized model that explains the development of relief in landscapes.[1] The model starts with the erosion that follows uplift of land above a base level and ends – if conditions allow – in the formation of a peneplain.[1] Landscapes that show evidence of more than one cycle of erosion are termed "polycyclical".[1] The cycle of erosion and some of its associated concepts have, despite popularity, been a subject of much criticism.
