Passive margins, created at the margins of rifted continents, are affected by thermal, isostatic, flexural, buckling (plate tectonic), and dynamic (mantle) stresses. Variations among these give rise to diverse topographic expressions. The geometry of rifting also has a major effect on topography. Thus, many low-relief margins lacking a fringing escarpment occur at the failed arms of triple junctions. Variations in lithospheric flexural rigidity influence the response of passive margins following rifting. Postrifting evolution of the continental hinterland is more readily explained by stresses related to plate tectonic processes than by the dynamic uplift over plumes.
