When rocks weather in place and no or only little transport takes place, the remainder develops as soil. Mass Movement - when hillsides are weakened by weathering, they may erode away slowly bit by bit, or they may move downhill as a large mass. Streams - carry much sediment and eroded soil away from weathered rocks. Meandering streams have channels that migrate back and forth across a floodplain, leaving oxbow lakes and sandy ridges as subtle landforms recording the stream s migrations. Sinkholes commonly form by collapse of the limestones and other rocks at the surface down into underlying caves enlarged by groundwater flow.
Stalagmites grow on the cave floor beneath dripping stalactites.
