Abstract
Neo and palaeo orogenic belts are employed for explanations of the landscapes of the world mountain systems. Textbooks explain that high and steep mountains are located only in the neo orogenic belts, which formed in Cenozoic and Mesozoic ages, and low and gentle mountains are found only in the palaeo orogenic belts formed in Palaeozoic age. This explanation is quite different from the actual distribution of the world mountains. Therefore some students may misunderstand on mountain landscapes in the world. The concept of orogene is not for geomorphology but for geotectonics. The mountain landscapes should be classified and explain by topograpy itself, relative height and steepness.
