Question
Who stated that the slope profiles are convex, plane or concave according to the circumstances of the uplifting action ?
The correct answer is
Penck
Penck's Slope Profile Theory and Uplift
Geomorphologist Walther Penck proposed a theory relating slope profiles to the rate and nature of tectonic uplift.
Penck suggested that the specific circumstances of the uplifting action directly influence the resulting slope profiles.
- Convex slopes might form under conditions of rapid or accelerating uplift.
- Plane slopes (or pediments) could develop during periods of constant or steady uplift.
- Concave slopes might be associated with waning or decelerating uplift.
Therefore, Penck connected the specific forms of slope profiles (convex, plane, or concave) to the dynamics of the underlying uplifting process.
