You've partially answered your own question, so to amplify:
Rainwater acidified by absorbed atmospheric carbon dioxide sinks through the joints and other discontinuities in the limestone upland's mass, dissolving the calcium carbonate that is the rock's main constituent.
Eventually the tiny initial conduits start to join and capture others, and discrete passages develop. The water emerges at a rising, resurgence or spring.

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.
They are formed by the deposit of minerals. They are left behind by evaporation.
Caves formed from minerals dissolving and re-forming typically occur in limestone, where acidic groundwater dissolves the limestone rock to create voids. As the water carries the dissolved minerals, it can re-deposit them as stalactites, stalagmites, and other cave formations when conditions change. Over time, these processes shape the cave environment.
A large hole formed when a roof of a cave collapses.
Harrison's Cave in Barbados was formed over thousands of years through the process of water erosion and chemical weathering. Rainwater mixed with carbon dioxide creates a weak carbonic acid that dissolves the limestone rock, creating underground cavities and passageways. As the water flows, it deposits minerals, forming the unique stalactites and stalagmites that can be seen in the cave today.
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.
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.
Crystal caves are typically formed through a combination of geological processes such as the seepage of mineral-rich groundwater, temperature changes, and pressure variations. Over time, minerals like gypsum, calcite, or quartz are deposited on cave surfaces, forming dazzling crystal formations. The specific formation process can vary depending on the type of minerals present and the environmental conditions of the cave.
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.
