Conceptual scheme for the evolution of landscape in a humid temperature climate
Fait partie de W.O. Kupsch fonds
Conceptual scheme for the evolution of landscape in a humid temperature climate. The transition from, late youth ti early maturity is marked by the disappearance of remnants of the initial surface and by smoothing (grading) of valley side-slopes. In early maturity, most of the landscape is occupied by valley side-slope; in late maturity, by the valley flats of streams. The dashed line on each block represents sea level.
