The essential reason why there is physico-geographical zonation is the regular dis-tribution of solar radiant energy on the surface of the earth as a sphere. With varioushumidity conditions and different altitude above the sea level, realistic situation of theearth’s surface ean change the theoretical distribution pattern of physico-geographicalzonation.
