Which outcome results from variations in drip-rate affecting stalactites?

💡 Explanation

Variations impact stalactite structure because of varying rates affecting the deposition of calcium carbonate via the mechanism of chemical precipitation; therefore, ring-like diameter variations occur, rather than full dissolution as that needs external erosive forces.
