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.
