As for the physical properties, limestone usually varies between very fine-textured rocks and coarse-textured rocks. Further, there are many different types and names of limestone like chalk, coquina, travertine, tufa, fossiliferous limestone, lithographic limestone, oolitic limestone.
Hard limestone rocks were also used for grinding stones (manos/handstones as well as grinding slabs), but harder stones, such as granite and other metamorphic rocks, were preferred. When limestone was the only rock available, that is what they used.
Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.
