it is when a stalactite and a stalagmite are joined as one.

Correct, but I do love that wording - sounds as if they've married!
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.
Harrison's Cave was formed by rock
by the limestone in the cave formed by dissolution by the limestone in the cave formed by dissolution
a cave
When rock above a cave collapses, a sinkhole is formed.

how was the titan cave was formed
Harrison's Cave was formed by rock
Ape cave was formed by a water erosion.
Erosion
A sinkhole is formed when the roof of a cave collapses.
by the limestone in the cave formed by dissolution by the limestone in the cave formed by dissolution
it is a 'karst' cave, i.e. formed by the action of water on limestone.
stalagmites
A table.
They are called columns. Columns are formed when a stalactite and a stalagmite are joined together.
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.
