		Penck disagreed strongly with Davis’ idea that land is rapidly uplifted, followed by a prolonged period of no tectonic movement during which erosive features wear down the uplifted land to a flat surface called a peneplain.
		Walther Penck was born in Vienna, Austria on August 30th 1888.
		Walther Penck’s life was cut extremely short when in 1923 he died of cancer of the mouth.

	Slopes (geography) - Printer-friendly - MSN Encarta
		These are slope replacement and parallel slope retreat.
		Slope replacement, first developed by the German geologist Walther Penck in the 1920s, involves an initial slope retreating as a result of uniform weathering and being replaced from below by a gentler slope.
		This occurs because the weathered material gradually builds up at the base of the receding slope, protecting it from further weathering.

	slopes
		However, their models are not necessarily contradictory, but reflect the different climates, tectonic settings, lithologies and processes affecting the slopes where they studied.
		William Morris Davis studied slopes in New England where the climate is humid and temperate and the tectonic setting is stable.
		Lester King worked in the-semi arid climate of South Africa and Walther Penck in the tectonically active Andes.

	Antiquity of landforms (Site not responding. Last check: 2007-10-30)
		Davis’s ‘cycle of erosion’ was immensely popular during the first half of this century, but it is mostly rejected today, especially because it is mostly hypothetical with no current examples of a ‘peneplane’ forming today at sea level (base level).
		The cyclical schemes of Lester King and Walther Penck have fared no better.
		These cyclical hypotheses were attempts to account for the many erosion surfaces observed over the earth.

		It is another very easy peak in the Puna and another one on which we made the first British ascent.

	GEOG315
		- assumption of a rapid uplift questioned by Walther Penck because the overall forms of a landscape depended on whether the rate of uplift is increasing, decreasing or constant through time
		according to Penck, the principal mechanism of change in slope profile is through slope replacement;
		In general, Penck believed that landforms should be interpreted as a balance between erosional processes and diatrophic (uplift) processes
