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.
Rain
After a flood, the water level drops as water recedes or evaporates. This process occurs as the excess water drains away through rivers and streams or soaks into the ground. The decrease in water level is a natural response to the balancing of water supply and demand.
The process in which water filters into the bedrock is called infiltration. This is when water soaks into the ground and moves through the spaces between rocks and soil particles.
Because X-rays can't penetrate Earth's atmosphere. In other words, the air soaks them all up, and none reach the ground. So an X-ray telescope located on the ground would never see any, and would be quite useless.
When a potato chip soaks in vinegar, it may absorb some of the vinegar, causing it to soften and lose its crispiness. The vinegar can also add a tangy flavor to the chip.

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.
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.

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.
