In this hall it introduces the action of water, wind, ice and sea wave to the earth’s surface to form various geological landforms. It introduces the cause of valley, the kaste landform, desert, and so on.
Stalactite:
It is the unique production of kaste area. It is eroded by the wash of water to form kaste caves. The calcium carbonate solution drops to form mastoid shapes that it is called “stalactite”.
Level Grain Landform:
It is a sedimentary rock formed naturally by water force and sedimentary action. Through it we can see the creating ability of water, wind, and even ice action of the nature.
Kaste Cave:
The indiscerptible calcium carbonate turns to little dissolve hydrogen by the action of water and carbon dioxide. As the content of lime is different that the erosion is uneven, the rock is gradually eroded to various shapes of kaste caves.
