Landforms are the results of endogenic and exogenic forces of the Earth under the influences of tectonics, water, wind, glaciers, waves and time. They are the basis of physical and natural geography. Basic landforms include mountains, hills, plateaus, plains and basins. Landforms can also be divided into tectonic landforms and climatic landforms. Landforms are the frameworks of landscapes. Different scales and types of landforms can constitute different landscapes in the natural and geographical environment. They can also affect the climate and the redistribution of surface water and groundwater as well as the composition and distribution of biological communities. Landforms and the diversity of natural landscapes are important for providing tourism resources and for tourism earth science research.
