Pardon?
Chemical weathering, provided the rock can be dissolved by ground water, limiting it to limestone and gypsum.
mechanical weathering +++ I'd class it as chemical weathering because the action is dissolution by weakly-acid, and it works only in limestone, gypsum and dolomite - although dolomite deposits are not normally structurally disposed to cave development.
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.
Infiltration
infiltration
It means that the ground is porous.

precipitation is the water that soaks downward due to the ground trickles

Some water soaks into to the ground as runoff. This runoff can then become part of the local water table.
