Geologic Structures are reflected on the landform development. So lots of studies are emphasized on the individual processes and mechanism of the relationship between geologic structures and landforms. In this study, many cases are represented, such as : weathering, stream directions and structures expecially joints, gnamas, meander bending etc. New D-D Diagrams and photos are available to explain the relations of two factors. Landform developments are depend on geologic structures.

There are lots of depression forms and closed small hollows in the Karst landforms. For example, doline, uvalas, corrosion plains are belong to this case. In Karst surface it can be find that the gorges, meander caves, natural bridges, blind valleys, steepheads and dry valleys are well known landforms.

The purpose of this study is to grasp the distribution characteristic of tour cave in northeastern Asia. It is examined to use internet homepage to get the status of tour cave in northeastern Asia. First, the total of tour cave is 116 and, in type limestone cave is extremely many. Second, the distribution character by nation has been shown China, Japan and South Korea in sequence. In the type tour cave, China, South Korea and North Korea are more popular with limestone cave while Japan, Taiwan, and Hong Kong have more marine caves. This study mainly relies on the research of internet homepage. Therefore, after this, activated research about tour cave is needed through comparison and analysis with more concrete statistical data and tourist behaviour by nations

This Study is about the wetlands in the GyunggiDo Mountains. It is written in the point of the hydrogeomorphology, geology, and soil. And it has accessed to ecological environment. Wetlands are divided into mountain wetlands and river wetlands by location, relief, processes, hydrology, and the type of inlet and outlet of water in wetlands. Mostly mountain wetlands are formed by the process of destruction of mountain slope. So they are to be located in the knickpoint. Therefore the underground surface is visible and underground water is rising or leaking. At this process, the environment forming wetlands are made by soil that was influenced by geology and composed by fine and very fine granules.
