Drainage patterns depend on the topography and geology of the land. Iowa can be divided into eight landforms based on glaciation, soils, topography, and river drainage. The mapping yields onshore topography as well as underwater elevations. Herzegovina has drier Mediterranean climate, with dominant karst topography. Maui's diverse landscapes are the result of a unique combination of geology, topography, and climate. Some globes have surface texture showing topography or bathymetry. Kalymnos is mostly mountainous with complicated topography. These cavities frequently collapse to form sinkholes that form part of the local karst topography. Israel also has a number of areas of karst topography. Derry is characterised by its distinctively hilly topography. Western Utah is mostly arid desert with a basin and range topography. Solution weathering of the limestone results in a "Bahamian Karst" topography. The area is dominated by ridge and swale topography. Each has unique climate, topography and fertile soil. Topographically, mires elevate the ground surface above the original topography.
