Document Summary
Water runs through the cracks and faults and breaks off the rock: tower karst. Remnant stumps are left behind from the original bedrock material: sinkholes. 2 types: solution sinkholes, result from the dissolution of the bedrock from carbonation, collapse sinkholes, the remaining material is too weak to support the structure and then collapse, disappearing streams. Streams that flow along the surface and then disappear. Flow into a collapse sinkhole into a subterranean cavern system: karst valleys. A sequence of sinkholes that have merged and grown together; looks like a river bed: all karsts are underlain by cavern and caves. Erosional (creates caverns: rock saturated with water, carbonation takes place, water carries off excess sediment, when water level drops, left with cavern. Water soaks down through bedrock, the droplet hangs on the end of the limestone, and when the water evaporates, the limestone is left: stalagmites. If those same drops of water are falling on the floor, they form stalagmites.
