A series of levels of the Earth surface organization is distinguished, such as space level, global, continental, local, and mesa-microlocal levels, different in forces and pattern of their action. Boundaries between the levels become less distinct with increasing the levels' rank, the exogenic factor gains in importance, processes characteristic of the levels require less time to become evident. Each level calls for individual methodical approach. The latter thesis is explicated with reference to the fluvial relief dynamics.
