Theory 67/Rock cycle/Onset phase
Weathering Starts on a Reaction Ratio
The claim
Rock breakdown begins when the ratio of reaction rate to erosion rate is high enough for chemistry to outpace removal.
01Mechanism
Weathering requires contact time; fast erosion removes material before it alters.
02Prediction
Weathering should track the ratio.
03Refutation
Weathering tracking rainfall would remove erosion.
