According to Walther Penck's theory of landscape development, which of the following statements best describes the process of slope retreat?
1
Slopes retreat at a constant rate as they are uplifted, maintaining an equilibrium profile throughout their evolution.
2
Slope retreat is significantly influenced by the amount of vegetation cover, which stabilizes the slope against erosion.
3
Slopes retreat without significant changes in form, as uplift rates are balanced by denudation rates, leading to "parallel retreat".
4
Slope retreat is a secondary process that occurs after the primary stage of landscape levelling and is mostly influenced by chemical weathering.
