mechanical weathering is acid rain causing pieces of the rock to form together
Principally chemical as the limestone is dissolved by carbonic acid (rain-water acidified by absorbed atmospheric CO2). As the cave develops mechanical weathering of its stream-passages may contribute, by abrading the rock with sand carried in the stream.

Weathering
Right - rain absorns atmospheric CO2 to become slightly acid. When this water percolates through discontinuities in limestone, the rock is dissolved by this carbonic acid (an example of chemical weathering), and over time the conduits this creates enlarge and coalesce to form caves.

acid rain
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.

By weathering and erosion. The types of weathering used is:physical weathering- when a plant grows inside a rock and the roots break it apart; abrasion- mechanical weathering - erosion- and chemical weathering - acid rain, water weathering and erosion.

Naturally speaking, the rate at which limestone dissolves depends on the amount of rainfall and the concentration of carbon dioxide in the water. Chemical weathering is the process that breaks down rock through chemical changes. The most common agents of chemical weathering include water, oxygen, carbon dioxide, and living organisms. Chemical weathering creates holes or soft spots in rock, so the rock breaks apart more easily. Chemical and mechanical weathering often goes hand in hand; mechanical weathering breaks rock into pieces, exposing more surface area to chemical weathering. It someone wants to dissolve a rock manually, Hydrofluoric acid is the answer.
Yes that's true.
