Carbonation
chemical weathering
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.

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.

The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.
Physical weathering is a type of weathering in which minerals react with dissolved oxygen in water. This causes chemical changes to take place in the minerals.

Clastic sedimentary rock is the usual type of rock formed from the products of rock weathering.
