Geomorphology is a scientific study of Earth's surface and poses that happened to him. Broadly speaking, associated with the landform (land form) eroded from the rock hard, the shape formed by the construction of rock debris, and sometimes by perolaku organisms in which they live. "Surface" (surface) should not be interpreted narrowly; must include also the most distant Earth's crust. Appearance of subsurface, especially in areas where limestone is very important cave system formed and is an integral part of geomorphology. The effects of erosion by water, wind, and ice, in collaboration with latitude, altitude and position relative to the water laiut. Can be said that each region with specific climatic characteristics also have their own views as a result of erosion that works differently to the existing geological structure. Incision of water on a hard limestone layer can form a permanent river flow and periodic, can also be a drainage channel that passes through the weak parts. To form a basin-basin on the yag eroded and left the higher part of the hard eroded. The size of this basin and the height can be several centimeters to several kilometers. Morphology of macro Below are some forms of surface karst morphology meters to kilometers in size:
* Swallow Holes: Locations where surface flow entirely or partially from a subsurface flow contained in the limestone. Swallow holes contained in the Polje is often called ponor. (Marjorie M. Sweeting, 1972). This
