GEOLOGICAL STRUCTURE . Unlike South America, millions of years ago was part of Gondwana, North America – a fragment of Laurasia – the Ancient continent of the Northern hemisphere. The basis of North America is a long Precambrian North American platform . In the North-East of its crystalline basement, composed of granite and gneiss, comes to the surface in the Canadian shield . In the rest of offset by a strong Foundation layer of sedimentary rocks (Sandstone, limestone).
From all sides of the platform in different geological time were “Built” folded area. In particular, strong folding formed on the approach to the site of the Pacific – North American lithospheric plates .
More than 10 thousand years ago the climate of the Northern hemisphere was much more severe: snow fell during the long winter, not had time to melt and accumulate. Gradually it turned into ice. As a consequence, on the North of the continent was formed by a giant glacier covering. Hundreds of years he moved to the South along the uneven surface of the continent. In ice versely large and small fragments of rocks Continue reading
Moves under the world
Polish researcher Jan Pink argues that system of ancient tunnel covers the entire planet, including the ocean floor. The tunnels seemed to be burned into the surface of the earth. Their walls are hardened melt rocks that look like glass. Modern humanity is similar tunneling technology is unknown.
The oldest tunnels, whose age is estimated at nearly a million years, was found in 1965 by the Argentina ethnologist Juan Moritz. In Ecuador, in the province of Morona-Santiago, his expedition explored and mapped the system of tunnels, mostly rectangular, running at a depth of 230 meters. Their smooth walls seem to be polished. They are ventilation pipes with a diameter of about 70 centimeters. These mysterious underground structures extend for hundreds of kilometers in different directions, including towards the Pacific ocean. Most of them still remain unexplored.
American specialist Andrew Thomas is convinced that the ancient underground tunnels penetrate the North American continent and connect it with Europe and East Continue reading
The ARCHITECTURE, the art and science of building.
The earliest architectural structures provide only partial protection. The Bedouin tent or the Indian wigwam served as shelter from sun, wind and rain, but almost failed to keep out the cold; in a needle Eskimos also found refuge from wild animals.
But man seeks to embody in the forms of architecture and his pursuit of the beautiful, their ideas and hopes. Every piece of architecture is design but not all design becomes a work of architecture.
The architecture has three fundamental characteristics. First, the building should meet its intended purpose. If you understand the functionality of the building according to its purpose, then, in the words theorist of functionalism of Louis Sullivan, the best buildings of all time were functional. Secondly, in addition to utilitarian purposes, the architecture expresses the spiritual needs of a person, consisting in the creation and contemplation of beautiful, harmonious images. The third criterion for evaluating architectural structures such as its reliability.
Designs of buildings are determined primarily by the tastes of the people and the spirit of the time.
Architecture requires visual unity, artistic integrity, whatever functions may have the construction. The various elements should fit each other, and each element a. Continue reading
