Limestone is broken into pieces by the actions of animals. What effect would this have on the rate of chemical weathering of the limestone.

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.

Ithink that its like 15 mph.
