Harrison's Cave was formed by rock
Ape cave was formed by a water erosion.
A sinkhole is formed when the roof of a cave collapses.
The cave is thought to be the biggest in Britain. It is thought to be 460ft deep and as high as the London Eye. It is made of limestone and shaped by rain water over millions of years and it is big enough to house St Paul's cathedral several times.

stalagmites
Stalactites. You may also notice distinct erosion patterns in many cave ceilings, formed when the passage was filled with water at an earleir stage in the cave's development.
fingals cave is a cave formed by the same geological processes as those at the giants causeway on the other side of the Irish sea. after a volcano erupted 60 million years ago, hexagonal basalt columns formed as the cave cooled. the cave which has been formed by the sea eroding it away is easy to access. it was discovered in 1772 by sir Joseph banks and a visit to the cave by the composer Felix Mendelssohn inspired him to write his 'Hebrides overture''. popularly known as ''fingal's cave''.+++Not quite: the columns formed as the rock cooled. The cave did not exist until long after the island formed, and was then, as you say, cut by erosion. The volcanism was associated with the inception of the Atlantic Ocean.
