The question asks about a specific term introduced by Crickmay to supplement or modify the concept of 'peneplain', originally proposed by Davis. Crickmay disagreed with aspects of Davis's theory and proposed a related but distinct term.
Crickmay's Panplane Term
Geomorphologist Albert Banner Crickmay, while discussing landscape evolution and erosion surfaces, proposed the term Panplane. He felt the concept of a peneplain, as defined by William Morris Davis, did not fully encompass certain landform characteristics he observed.
- Davis's Peneplain: A nearly flat surface of low relief, representing the final stage of the cycle of erosion.
- Crickmay's Supplement: Crickmay introduced Panplane, suggesting a surface formed by the coalescence of pediplains, which he considered a more accurate representation in certain contexts than the traditional peneplain. He proposed this term to refine the understanding of extensive, low-relief surfaces.
Therefore, Crickmay supplemented the concept of peneplain with the term Panplane.
