The biggest parcel of the people who make this daily passage, searching the proper survival, works in jobs that request man power of low qualification or conquest its incomes in the informal market. Others look the cities of the DF to have access the health and educao' ' (Queirz, 2006). This evidences low the quality of life of the inhabitants of the Entorno, therefore they need to dislocate from its habitual housings to not only look the survival, but also the services of health and education that are not offered in the cities where inhabit, thus generating an overload in the services offered for the high demand of the Entorno, fact that I eat we can observe has its roots in the construction, distribution of the use of the ground and in the urbanization of Brasilia, as it affirms BLACKSMITH and PAVIANI (1985): The migrante population formed slum quarters and encampments in the space in construction. To shelter this population peripheral nuclei to the Plan had been created Pilot, as solution to hinder the disordered growth in the center. It is initiated, then, a process of space selectivity and segregation, that if accents with the coming of new migratory contingents and with the posterior transferences of slum quarters and encampments (BLACKSMITH and PAVIANI, 1985, P. 51).
With regard to the segregation of the Entorno of the DF, Queiroz (2006) it affirms, ' ' One of the forms clearest of if segregating a society is not offering apparatus of basic infrastructure and social equipment in the localities most devoid and of population of low renda' '. The phenomenon of the pendular migration is a signal on that the there resident population and that depends on the services of another locality is being excluded of certain necessary apparatuses for the good functioning of the society. The public politics aiming at the attendance the collective necessities of the people esbarram in the bureaucracy to divide the jargon of responsibilities on the quality of life of the population with the neighboring States without taking in account the influence that Brasilia exerts in the regional and national context since its creation.
The hurricane is a powerful storm that produces fast ventosextremamente. In the reality, the hurricane is a cyclone (a depression) deforte intensity. When the hurricane reaches the continent, it provokes chuvastorrenciais of great intensity in a short interval of time. The hurricanes are formed later that the rays of the incidemdurante Sun some days on the ocean, provoking the heating of the arsituada mass of next to its liquid surface, when its humidity if raises. In the interior of hurricanes, the 117 winds vary of km/h 300km/h.
According to its intensity, the diameter of the hurricane can reach the 2,000 quilmetrose can be dislocated for some thousands of kilometers. Some are dislocated to the speed of 20 25km/h, although the extreme speed of makes ventosque it to turn. A curious fact and notable are that in the center eye of the hurricane atempestade is calmer. In this zone, the pressure is very low, being able ocorrerventos of only 30 km/h. Cyclone: it is a violent storm that occurs in quese forms in waters tropical and hot and it system of area of low atmospheric pressure in its center can arrive at one velocidadede120km/h, osventos blows for inside of this center with closed circulation forming famosoolho of the cyclone, in the hemisphere North, the winds turns in the counter-clockwise direction; in the South, the clockwise one.
ExtratropicalSistema cyclone of area of low atmospheric pressure in its center. Also called detempestade extratropical, 12km/h can arrive, it is generally consideradoum migratory cyclone found in the averages and high latitudes. TropicalSistema cyclone of area of low atmospheric pressure. Beyond if developing on asguas tropical due ace high temperatures and humidity, it if put into motion deformed circular organized. Depending on the sustentation winds of the surface, the phenomenon can be classified as tropical disturbance, tropical depression, tropical storm, hurricane or tufo.
