The highest of hills in this picture show fairly similar heights making up a summit accordance. Aerial photograph from the Altai region of Russia.
A summit accordance exists when hill and mountaintops tops, and eventually also plateaux, have such disposition that they form a geometric plane that may be either horizontal or tilted. Summit accordances can be the vestiges of former continuous erosion surfaces that were eroded.[1] Other proposed explanations include:[2]
- the possibility that erosion is more effective at height tearing down mountains that stands out
- that isostacy regulates the height of individual mountain masses meaning that small mountains might be uplifted and large mountains dragged down
- that landscape dissection by uniformly spaced streams eventually reach a state in which summits reach similar heights
- that summit accordance is derivative of structural surfaces exposed by erosion
