Cymatogenic Earth Movements
Geomorphic processes, both exogenetic and endogenetic, use the earth’s internal energy as the source of power. These, in turn, are the base for the formation of all the landforms on the earth. The atmosphere or the climate further modifies these landforms. The atmosphere and climate acquire energy from the sun.
Hence the landforms are not the result of just one force but it is the result of an extremely complex system of processes derived from the interaction of earth material resistance on the one hand and tectonically and climatically derived forces on the other.
Endogenetic processes which emanate from within the earth’s crust and include crustal or non-isostatic warping within the mantle (eperogenesis), earthquakes, folding (orogenesis), faulting, metamorphism due to heat flow and volcanism.
In 1959, L. C. King introduced the concept of Cymatogency, whereby a landscape, often hundreds of kilometres wide, is either arched or domed to thousands of meters with minimum rock deformation. According to King, modern mountain ranges are usually cymatogenic, not orogenic, and any local rock deformation is presumed to antedate the simple cymatogency that, followed by erosion and valley cutting, has created modern-day mountain terrain.
