The construction of the Egypt Pyramids, evolution of the civilization and climate change

La construcción de las Pirámides de Egipto, evolución de la civilización y el cambio climático

Abstract

The construction of large buildings by different civilizations has been a way of leaving evidence to the future world of its power and well-being. The works became the center for generating a source of jobs, resulting in economic expansion in other activities such as food related to agriculture and animal husbandry. He because of the pyramids constitutes a very specialized religious-social issue, which is not extended in the present investigation, based on the existence of a megaproject that would be developed in stages according to the life of the pharaohs of the different dynasties. The orientation of the sides of the pyramids with high precision with respect to the north-south, as well as their arrangement according to the constellations, are results of a high degree of knowledge about instruments for measurements and orientation. For the Cheops pyramid, the exploitation of the quarry to obtain more than 2,300,000 blocks of rock, requires basic principles of geology, based on its dimensions in stratification planes and so-called diaclases, generally forming orthogonal fracture patterns. Likewise, the transport of the blocks and their placement constitute basic principles of civil engineering, related to a landscape of forests, where the exploitation of the wood constituted the main element for transport through the roller system and its placement required adequate ramps slope supported on scaffolds constructed of processed wood.The current desert climate covered by sands, contrasts with the climatic conditions that existed during the development of the civilization of the Ancient Empire of Egypt, a Mediterranean climate with abundance of forest landscape. Climate changes have occurred in recent millennia, where civilizations have adapted, with the ingenuity to evolve to better well-bei.
