Anyone who has ever been in high mountains knows the striking structures in the rocks: folds of varying size and shape. Sometimes whole mountain ranges look like pushed together as a tablecloth. This sample shows very accurately the cause of rock folding. In most cases folding occurs by narrowing the earth’s crust. Therefore, wherever tectonic plates are colliding earth’s largest, more or less folded ranges of high mountains are arising as mountain chains. These are for example: the Alps, the Himalaya, the Andes, the Rocky Mountains, the Caucasus, or the central mountains of Papua New Guinea. |
