Peltier Weathering Graph

Louis Peltier American physicist and climatologist 1950 study “The Geographic Cycle in Periglacial Regions as it is Related to Climatic Geomorphology” His graph attempts to predict the type and rate of weathering at any given place on Earth Doing so from its mean annual temperature and mean annual rainfall.
