http://www.mbbcollege.in/db/notes/511.pptx WebParallel retreat A slope maintains a constant angle as erosional retreat of the ground surface cuts back into the bed rock found in arid environments. Slope decline Occurs as steep slopes gradually become shallower, flattening the overall slope profile. Then end result is a profile with a convex upper slope and a concave lower slope.

WebParallel Retreat The climate, rock type, and rock structures are the most important factors in slope erosion. As previously noted, rocks of different compositions weather at different rates—harder rocks form steeper slopes and generate coarser‐grained, more angular talus slopes that are resistant to weathering and erosion.
