Abstract
The purpose of this essay is to understand the relationship between litology and the units of relief aiming the comprehension of the spacial organization of these forms in the Brazilian territory. It is supposed that this relationship expresses itself through one association key between these units of relief, the litology and altimetry, and finally the elaboration of a representative map of distribution of forms of relief through the Brazilian territory. The elaboration of a map started with the adaptation of geomorphologic mapping ever produced by IBGE and also Ross. The scale of work for the elaboration of the map of relief units is 1:5.000.000 because it is the most appropriate to represent the Brazilian territory, the geologic provinces, the macrocompartments and macro-structures of the relief of the country. Specifically, it is intended to comprehend how the litologic parameters can influence the spacial forms of relief. It is understood that the concept of morpho-structure is related to the influence of the geologic structure in the genesis of the forms of relief, mainly those which are related to the action of the dynamic of geologic provinces, and the concept of morpho-sculpture relates to the influence of the past and present climatic actions on a determined structure. While the morpho-structure associates in one special unit of relief similar forms in according the dynamic actions of the endogenous processes of the relief, the morpho-sculpture associates the dynamic actions of the exogenous processes .It is emphasized that what predominates in the Brazilian territory is the planaltic relief, which happens from the
