Rule of Territorial Differentiation
Geographical differentiation is a universal rule of geography that forms the foundation for explaining the diversity and order of natural landscapes. It includes latitudinal zonality and non-latitudinal zonality. Zonal differences are induced because solar radiation is unevenly distributed on the surface, which leads to natural variations from south to north. Non-latitudinal differences refer to the land-sea distribution, topography, and tectonic factors caused by the internal energy of the Earth. The disparities caused by these influences include the differences in dryness and humidity caused by the distance from the ocean and the vertical differentiation due to topography. The differences in landscapes within a tourist area are also a reflection of this concept.
