Acidic ground water (rain-water that has absorbed atmospheric carbon dioxide to form carbonic acid) dissolving the limestone as it flows through the joints & other discontinuities in the rock mass.
Rain or snow-melt water absorbs atmospheric carbon dioxided to create the wek carbonic acid, which over time in percolating through the limestone mass's joints, bedding-planes and faults, dissolves the rock's primary mineral calcite (calcium carbonate).

In all limestone caves, the same as as is "evident" - by the cave's very existence - as in all the limesrtone caves and other karst features in your country - chemical weathering! (Dissolution by carbonic acid.)
It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
Weak acids seep into the ground until they reach a zone soaked with water. As the ground water become more acidic, it dissolves calcite and other minerals in the rock. Over time, the action of the acidic water produces holes in the rock. The holes grow, creating passages, chambers, and pits, and eventually become caves.

large caves in limestone bedrock

Caves can be found in really any place with chemical or mechanical weathering. ++ They can but by far the vast majority of the world's caves are formed in limestone by it being dissolved by percolating water.
It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.
Chemical Weathering .
The same type evident in all limestone caves, and in your country too!Chemical weathering - the limestone is dissolved by weakly acid water flowing through them. Some mechanical erosion by abrasion in high water, but this is a secondary mechanism.
Limestone caves are created through the process of erosion by water. The erosion follows chemical weathering: the water dissolves the limestone. A karst landscape is formed when water flows through soluble rocks such as limestone, dolomite and gypsum. Limestone dissolves away through the reaction of water.
Same as in any caves of the same types anywhere in the world, which in karst caves is dissolution of the host limestone by weakly-acidic ground-water.
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
