The model of Speleothems is movable. The kind of model also has cave animal, cave plant, and railroad model besides Speleothems. Speleothems currently exhibited are stalactite, stalagmite, ice stalagmite, lava ball, Piller, etc. Otherwise, railroad models are the form of JR of a blue color, and the form of purple Hankyu. Some rails stretch a net and it makes it a form like a tunnel.
Cave organism has trogloxene, cave fish, cave flora, troglodyte, etc. The feature of cave organism is as follows. Degeneration of the compound eye, after spring, and tracheal gill with the thin skin whose coloring matter is lost is progressing. Furthermore, a leg, a tactile sense, and sensitive hair are developed. On the other hand, there is no periodicity of a life and the slow-growing egg production is decreasing.
Weathering is the phenomenon in which the surface part of rock deteriorates by action of a temperature change and water. This phenomenon is the case of the weathering by a temperature change. Furthermore, it is the case where freeze expansion of water grinds.
A volcanic eruption thing flows a lignosa belt. Then, if lava touches a trunk tree, it will cool and it will become hard. A basic form is divided roughly into vertical tree-mold, rucumbent tree-mold and a compounded tree-mold. Various types will be generated if environment differs in addition to it.
A cave waterfall is a mechanism which the lava in a cave flows and is made by the fall of the floor of a steep slope. The operation of a cave waterfall and a geyser used the water of a cave pool. It is a model which is dropped from a ceiling part, is one side and carries out a fountain to things. LED constitutes the changing illuminations.
A cave pool says the volcanic crater or volcanic depressed ground which has stagnated for the mobility of basalt. It is used not only for fluid lava but for the state where it has solidified. It is the mechanism in which a bat flies after a cave pool. It is the model which had underwater the system which lets a fish swim.
