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. Other proposed explanations include:〔 〕 *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 ==See also== *Dissected plateau *Syrt 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Summit accordance」の詳細全文を読む スポンサード リンク
