NATURAL DISASTERS

In the geological evolution of our planet Earth, our Earth's crust has undergone processes of adaptations and modifications to its geological and climatic conditions. The processes of our planet adjustments often cause natural disasters, which are caused by factors related to erosion, weathering, sendimentação, movement of tectonic plates, and other factors that may cause losses and biological materials.To better understand the subject we have listed some instances more recently recorded in our planet.Volcanoes and earthquakes - earthquakes occur due to collision and separation of the tectonic plates. Volcanoes that expel substances at high temperature within the earth, melting glaciers may exist in craters.Tsunamis - may be caused by undersea earthquakes, volcanic explosions or meteor in the sea.Falling meteors - In scientific papers, a meteor wiped out the dinosaurs 65 million years, are rocks that interspatial trajetam for space and can fall into Earth's atmosphere causing destruction of land, plant and lives.Climate Change - The Earth goes through periods of glacial and interglacial 20,000 years to 10,000 years, in which there is increase in sea level. Global warming, which occurs from the intensification of the natural phenomenon of the greenhouse effect by air pollution may accelerate the process of global warming causing imbalances and disasters such as the melting of glaciers.Whether by human interference or by the natural fit of the components of the planet, the resulting natural disasters in recent times has demanded of the rulers and societies of various countries, prevention policies and action relief to victims of regions hit by cyclones, earthquakes and climatic imbalances . Regarding climate, humanity simply rethink their stance of civilization and economic growth in building a sustainable and equitable between man and nature.
