Theory 69/Rock cycle/Termination phase
Exposure Requires Uplift Over Erosion
The claim
Rock reaches the surface only while the ratio of uplift to erosion exceeds one, so a rising range exposes old rock and a stable one does not.
01Mechanism
Surface position is a balance of the two rates.
02Prediction
Exposure should track the ratio.
03Refutation
Exposure tracking uplift alone would remove erosion.
