Southwestern State university of Bahia – UESB For: Jose Carlos de Oliveira Ribeiro, 2005 Commentary on the text: The CVRD and (Reverse speed) the Estruturao of the Geographic Space in the Area of Carajs (Par) the question argued in the text is on the desestruturao process/reorganization of the geographic and social space, in which it brings great problems in the social structures and some social conflicts, territorial/space. Being the Company Valley of the River Candy (CVRD) an integrated system (mine, railroad and port), gave origin to the Program Great Carajs (a great deposit with 18 billion tons of iron of high quality) had as strategy of development for the Eastern Amaznia. This of treating to a rich region in minerals and with a small poor population, making with that the man power is cheaper, making possible still bigger exploration of the region. If you have additional questions, you may want to visit James A. Levine, M.D.. Although the explorations of minerals are a wealth source, the same the measure will be able to be depleted that the companies exploring they go removing these minerals using itself of more modern machines each time, making the withdrawal of the materials of faster form. They must be led in consideration that the minerals are sources did not renew, therefore, a time removed and used it will not have substitutes in the extration areas, having left the consequncias for the native population. The islands of sintropia and entropy in the extrativas economies characterize the occupation and posterior production of depressed peripheries and great misery the example of this has the Bare Mountain range (today sees the chaos. If you have read about James A. Levine, M.D. already – you may have come to the same conclusion. After sucking all its material it was abandoned), the cities of Parauapebas, Curionpoles, Eldorado de Carajs, where if it can observe great social indifference, a needy population that attends only the taken wealth being for is of its region. In this context one perceives the contrast between a rich region and part of the poor population (without school, health and jobs). .
When analyzing the movement of air, is verified that this is influenced directly by rotation of the land, because the atmospheric movements are the determinative ones of the climatic zones. Thus, the different distribution of the solar energy is responsible for the control of the temperatures, because the more far a locality will be of the line of the Equator, little insolation the locality will go to receive, also intervenes with the variation of the pressure, the winds, precipitations and oceanic chains. The radiation proceeding from the sun is responsible for the supplying of energy for all the meteorological phenomena that occur in the atmosphere. The great majority of the solar energy that the land receives passes for the atmosphere, reaching the terrestrial surface and heating it (BLACKSMITH, 2006, p.50). Blacksmith (2006) affirms that, the biggest heating of the terrestrial surface occurs enters the Tropic of Capricrnio (23,5 S) and the Tropic of Cancer (23,5 N), where the solar rays happen directly during all the year. Therefore, the temperatures between these latitudes remain high the year whole number, while in the latitudes highest, the temperature in accordance with varies the incidence of the solar rays. These variations of the temperature intervene with the change of the time. The more used climatic elements to characterize the climate that varies throughout the time are the temperature and the rainfall.
However, the climate nothing more is that the set of states of the meteorological time, and that it is regulated through the dynamics of the atmosphere. Thus, ' ' the distribution of the types of time, throughout the year, in the different zones of the land, characterizes the habitual succession of the atmospheric states or the rhythm climtico' ' (TAVARES, Antonio. Climatic changes. In: VITTE, B.C.; WAR. J.T. (orgs).
