The concept was pioneered by (1850–1934), who proposed that landforms evolve in a predictable, "orderly" sequence following a rapid tectonic uplift.
Early-stage features like waterfalls, rapids, and upland marshes typically vanish as the riverbed reaches a more stable, graded profile. Theoretical Context: The Geomorphic Cycle mature land pictures
In the mature stage, a landscape reaches its , meaning the difference in elevation between the highest peaks and the lowest valley floors is at its greatest. The concept was pioneered by (1850–1934), who proposed
Valleys remain V-shaped but deepen significantly. Major "trunk" streams begin to widen their floors, creating narrow floodplains where they may start to meander . Valleys remain V-shaped but deepen significantly
Modern geomorphologists often favor theories like John Hack’s Dynamic Equilibrium , which suggests that landscapes reach a "steady state" where they constantly adjust to energy inputs rather than following a fixed aging cycle. Scientific Resources & Perspectives
Streams are plentiful and well-integrated, forming complex branching networks.
The broad, flat uplands characteristic of the "youth" stage disappear. They are replaced by sharp, narrow divides between valleys.
