Caves below Us

In most limestone mountains spectacular caves are found below the surface, these are natural creations. The formation of these caves is largely contributed to water. Rain water seeps into the ground and dissolves the limestone as it flows downwards, the cracks and crevices so formed gradually enlarge to form small caves. Adding to this is the flow of underground water, most caves of this type either have water flowing  in them or have evidence of dried up river beds. Their creation by water is also substantiated by the presence of a large number of limestone ,deposits in the form of pillars, hanging from the roof or formed on the floor, which are called Stalactites and Stalagmites. Water also creates caves along the coastline as a result of quicker erosion of softer rocks. Other kinds of underground caves are also formed in basalt rocks as a result of quicker cooling of molten lava on the surface which allows the lava underneath to flow away to a different place thus leaving an empty space in the form of a cave.
