Description :
In studying the origin and evolution of landscape, various scales are used both in space and time. The A. suggests distinguishing the following effective time scales of landform evolution : formative extreme events and secular processes, clusterings of events, phases of higher frequency of extreme events, cyclic changes of longer duration. The assumption about positive correlation between size and age of the forms is frequently not valid. The A. underlines 3 principal regularities in relief evolution : way to destinity (planation), continuous adjustment to new conditions, coexistence of diverse forms controlled both by tectonic and climatic factors as well as by lithology.
