Weathering and Erosional Processes
Presented
by Lisa White
San Francisco State University
Interrelationships of climate and topography are important
-
Altitude affects rainfall and temperature, which in turn affects erosion and topogrqphy.
-
Mechanical erosion exposes new materials to chemical weathering and Chemical weathering increases ease of fragmentation of rocks.
Mechanical Weathering:
Physical fragmentation producing blocky, angular materials. (Click at left to zoom)
Angular edges often round through time.
Granites often weather in spheroidal sheets. (Click at left to zoom)
