Chemical Weathering
CALCITE - cryastaline calcium carbonate precipitated from the ground-water that had dissolved it from the limestone above the cave. Calcium Carbonate is the primary constituent of limestone.
No. That is mechanical weathering. Weathering by sand or other matter carried in the wind is a special kind of mechanical weathering called aolean weathering. Weathering by acid rain is an example of chemial weathering. Limestone is particularly subject to this. Illegibility of tombstones in old garveyards provide a good illustration of this.
Not sure quite what you are asking about, but anyway it is more accurate to ask what kinds of rock hold the caves, not what rocks are in the caves. Most caves are in limestone, a sedimentary rock, irrespective of water-level. There are a few caves in igneous rock: lava-tubes in basalt-flows, but on land, not underwater. There are also a good many caves in marble, the metamorphic but still-soluble form of limestone; and again the water-level is secondary to the cave itself. A few caves exist in rock-salt, an evaporite.
This weathering is called ABRASION
Sedimentary
normally damp weather with a lot of rain or snow depending where you are in the world
Carbonic acid
igneous rock
differential weathering water wears away some areas but not all
The majority of aves are made up of limestone Stalagmite rocks
It depends on the cave. Since many caves are limestone (water carves it nicely), you usually find limestone. But granite is common in New Hampshire & Vermont.

Physical weathering
The 2 kinds of weathering are the Mechanical or Physical Weathering and the Mechanical Weathering.
It is water weathering
