Limestone pavements and swallow holes hollows are created on the surface of limestone They form where drift material falls into joints which have been enlarged
is formed when the joints in the limestone are dissolved away by the rainwater Limestone is dissolved because rainwater is a weak carbonic acid The joints which are widened and deepened by this chemical weathering are called
