If a explorer went into a cave what landscape will he see?

A landscape that is strictly formed by the erosion of water. Most caves are formed by the underground rivers leeching and eroding the softer layers of the earth like limestone. What is left is passages that have been eroded away and over time is ever changing. There will be stalagtites and stalagmites and crystals that have formed over the milenia. If interested, do a search on local spelunkers in your area. There are many clubs that go caving on a monthly basis. Its a lot of fun. P.S. Wear a hard hat. Hooweestik. Answer: The landscape or terrain formed by erosion described above is called a Karst terrain.
