The outer shell of the planet Earth can be divididir in different compartment: the hydrosphere (or water sphere), the lithospere (or scope of grounds and rocks), and the atmosphere (or the air sphere). The biosphere is the alive matter of the planet. It reaches thus in the other three scopes, although there are no permanent inhabitants of the atmosphere. In relation to the volume of the Earth, the biosphere is only the very thin superficial layer that superficially extends 11,000 meters under the level from the sea to 15,000 meters. One thinks habitually that the life was developed for the first time in the hydrosphere, to brief depths, in the ftica zone. (Nevertheless, at the moment esteem that the life was originated around hidrotermales sources in the depth of the ocean). Then, in the time, they appeared the multicellular organisms and they colonized the bentnicas zones. Photosynthetic organisms emitted, by means of chemical reactions, the gases until arriving at the present concentrations, especially the abundance of oxygen, that characterize to our planet. The life terrestrial it was developed then, protected of rays UV by the ozone layer. The diversification of the terrestrial species thinks that it was increased by ...  Read the rest of the entry...

However, climatic changes will unchain impacts for population in such a way, how much to the animals and plants, therefore it will modify the ecosystem. Being thus, it is analyzed performance human being giving emphasis the activities that degrade the environment and places the planet in alert. This research has as main focus to tell the alterations that come occurring in the climate, therefore successive changes intensifies the increase of the climatic phenomena. Thus, it is aimed at to alert the population that if not to change our habits we will provoke the destruction of our proper habitat. With this, one searchs to show the climatic alterations and, that it has the man as main causer of them. Of this form, the effect caused of it are explanam disastrous action human being, with the objective to acquire knowledge the population. Thus, it is looked by means of this work to take information regarding the changes that the planet comes developing, searching the interaction man-environment. The CLIMATE AND ITS CHANGES To unmask the dynamism of the atmosphere sufficiently require knowledge on elements and the climatic factors. This demands the improvement of knowledge in the area, what demand very study and technician-scientific ...  Read the rest of the entry...

The scientific development has helped you put in new foundations and think how you produce innovations, linked you the human activities of daily life, how that knowledge changes and creates new processor environments changing lives. This study aims you evaluate the concentration of nutrients in various organic compounds, determines the effects of each compound producing chemical characteristics, using different treatments of experimental design, collect and analyze samples will be chemical quantification of macro and micronutrients in organic compounds. Key words: nutrients, organic compounds, scientific development. 1 AVAILABILITY OF NUTRIENTS OF ANIMAL AND VEGETAL RESIDUES FOR 1,1 PASTURES Justification the technological advances had been notables in the last times, propitiating conditions for new learning, shared, much-needed knowing in the conviviality between the men. study it will have the importance to demonstrate the nutrients extracted of the compostagem, the nutricionais changes in accordance with the environment and organic composite incorporation and catinicas exchanges of the plants animal esterco, observing physiological and chemical aspects. To use in fertilizaes for improvement of the ground. The compostagem of nutrients in ecosystems of the pasture is a dynamic process that involves ground-plant-animal and the handling of these components.

Of his periplo by the archipelago Gardens of Reina, the Spanish cronista Antonio Perpi: in the middle of the spell when contemplating from those virgin places, elegant and practically spectacular of Reina of the Antilles, it published more ago than one hundred years (1889): country of Las Palmas, breezes and perfumes .la frondosidad of its forests, the beauty of its birds, the colorful thing of its mountains, the surprising thing of its caves, and pleasant of its matting and their oases seeded in its seas forming enjoyable, beautiful and charming archipelagoes.

From his bojeo by the then island Juana or Cubanacn, it could inform, to the Governor Nicholas de Ovando, in the Spanish, who Cuba is an island, and not a continent, as Columbus believed.
