lovetee · Answer

Yes formation of a limestone caver is a physical change because a carving does not change the substance (limestone) it is still a limestone.

Anonymous · Answer

The formation of a limestone cave is a chemical change, not a physical change, because it involves the reaction of acidic groundwater with limestone, altering its chemical composition. This process creates new substances as it dissolves the limestone and later precipitates calcium carbonate. Therefore, this transformation is indicative of a chemical change in the material's identity.
