Mammoth Caves - to give the right spelling - is a complex and extraordinarily extensive system of several connected caves, making it the world's longest known system; but it was developed by the normal karst processes that form caves in limestone. I.e. dissolution of the rock by weakly-acidic ground-water.
As for "was", if any of its passages are carrying streams now, those "active" passages are still forming.
Mammoth Cave is located in the state of Kentucky, in the United States. It is known as the world's longest cave system with over 400 miles of explored passageways.
how was the titan cave was formed
Ape cave was formed by a water erosion.
A sinkhole is formed when the roof of a cave collapses.
it is a 'karst' cave, i.e. formed by the action of water on limestone.
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.
5 million years ago
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.
The opening is called the cave entrance or cave mouth. It is usually an "exit" formed by flowing water.
a stalagmite
Fallen boulders, calcite formations and sediment! Mammoth Cave is a karst cave; formed within limestone.
Stalagmites are cave formations that are formed when water dripping onto the cave floor evaporates and leaves behind mineral deposits, building up over time to create a cone-shaped structure.
