Theory 42/Sinkholes/Ratio lens
Size Is Dissolution Against Infill
The claim
Sinkhole size is set by the ratio of dissolution to sediment infill, so a fast-dissolving but rapidly filling cavity stays small.
01Mechanism
Cavities grow by dissolution and shrink by sediment transport; the balance sets the size at failure.
02Prediction
Size should track the ratio.
03Refutation
Size tracking dissolution alone would remove infill.
