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.
The process of rainwater dissolving and eroding soluble rock, such as limestone, to create underground caves is known as chemical weathering. This happens over a long period of time as water seeps through cracks in the rock, dissolving and carrying away minerals to form cave systems.
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.
Rainwater that soaks into the ground is called groundwater. This water can replenish aquifers, provide a source for wells, and contribute to the overall water cycle.
When water soaks into the ground, it is called infiltration. This process involves the water moving from the surface of the soil downwards into the soil profile.

precipitation is the water that soaks downward due to the ground trickles
ground water
it rains
Some water soaks into to the ground as runoff. This runoff can then become part of the local water table.
