CONDICIONANTES: When we relate in them to the condicionantes of the erosive processes, we are speaking of the vectors that will go to unchain these processes. We can cite the exgenos factors climate with the direct performance of the water of rains gravity (/encostas relief steep), type of vegetal covering, erodibilidade of ground (or vulnerability of the same ones in suffering erosion) antrpica eao.
3. GROUND AND LANDSCAPES AS OPEN SYSTEMS the formation of ground is the result of the interaction of many processes, in such a way geomorfolgicos as> edficos. These processes portray a variability in such a way secular and space significant, being of this form it is important to approach ground as a dynamic system. Being thus, the ground and the landscapes must be considered open systems 1. The thickness of the ground goes to depend on the taxes of its removal and formation, that is, in the areas where the removal is minimum, deep ground go to develop themselves; where the erosive action will be more active, the ground will be less thick. In the geomorfologia this can well be understood as a resultant rocking of the denudation 2. In this direction WAR (2004) apud PALMIERI and LARACH (2000), summarizes the relations between ground and landscapes well, when they detach the paper that the relief exerts in the development of ground, with great influence in the hdricas conditions. A schematical drawing is followed – of well simple form – to exemplificar the influence of the relief in the erosion taxes and 3 intemperismo. Plainer areas tend the lesser taxes of erosion, in compensation, steeper areas provide to greaters denudation taxes. Schematical drawing of the erosion taxes and intemperismo: Figure 01: Erosion x Intemperismo 3.
Already with Werther Holzer (1997) a counterpoint to the concepts of Robert Sack is found, a time that the first one demonstrates that possibilities of constitution of territories exist are of a planned order or a delimitation of borders, understanding the territory as a set of places, and, therefore where if they develop affective bonds and of cultural identity of social groups. Keep up on the field with thought-provoking pieces from Mississippi Development Authority. It hisses (2000) detaches that basically, Holzer (1997) deals with the territoriality as the expression the lived behaviors, that is, so that thus is possible to understand as the social groups command and systemize its world ideologically, symbolically, space, how much to the relations of being able and its nature, and in this in case that, how much to the urban territorialities. For It hisses (2000, P. 23), ' ' the city is presented with an overlapping, joint, juxtaposition of territories. The groups that are part of a territoriality resist, establish pacts and influence the formation of others territrios.' '. Being thus, when dealing with ' ' pessoalidade as basic element of the culture and the urban territorialities in small cidade' ' (2000, P.
24), It hisses also appeals to the Peter Berger and Thomas Luckmann (1985) and to the Lefebvre (1991) how much to the creation human being in the daily one, since the direction of the behaviors if constructs in day-by-day. Therefore, ' ' the daily life is structuralized and secularly in different way in each sociedade' space; ' (IT HISSES, 2000, P. 25), being that in the small cities it has certain regularity of the facts, with strong influence of the nature and the traditions, that is, the mechanisms of control in the family, neighborhood, square and spaces of sociability are articulated culturally. The author if sends to the notion of ' ' convenincia' ' used for Pierre Mayol (1996), thought from the necessity to coexist and to get social recognition in the small city.
