Hypsometry: continents against ocean floor.
A plate is continental or oceanic, and that one bit is what gives Earth its
bimodal elevation histogram — means near +0.8 km and −3.7 km with very little
ground in between. The blend across a boundary is what stops it being a step:
F2 − F1 is zero exactly on the boundary and grows inward, so the two
plates' bases mix over a margin instead of meeting at a cliff.
A stagnant-lid world has one plate and takes the null branch, which is the
swell alone — unimodal, which is Mercury.
