Limestone is weathered by mechanical and chemical means:
Mechanical: plant root growth in cracks and crevices, frost wedging, rock falls, abrasion.
Chemical: exposure to fluids containing acids--particularly rainwater and flowing runoff that is naturally acidic--that chemically react with the calcium carbonate in the limestone, dissolving it.
Limestone is weathered by water (rainwater) that erodes the rock away and forms underground cavers and gorges.
All types of rock can be weathered if near enough to the surface.
Relative to other rock types, limestone is on the 'easily weathered' end of the scale.

The rock tripoli is considered a siliceous limestone, as most of the calcium carbonate has been weathered out or baked out by proximity to a plutonic intrusion.
