[Answer] Why does differential weathering occur?

Answer: Different minerals have different resistances to weathering.
Why does differential weathering occur?

Thu Aug 15 2002 14:30:00 GMT-0400 (Eastern Daylight Time) · Weathering is the breaking down of rocks soils and minerals as well as wood and artificial materials through contact with water atmospheric gases and biological organisms. Weathering occurs in situ (on site with little or no movement) …

Causes: Vibration undercutting differential weathering excavation or stream erosion Slides Edit “A slide is a downslope movement of soil or rock mass occurring dominantly on the surface of rupture or on relatively thin zones of intense shear strain .”

Differential erosion – Erosion that occurs at irregular or varying rates caused by the differences in the resistance and hardness of surface materials; softer and weaker rocks are rapidly worn away whereas harder and more resistant rocks remain to form …

Spheroidal weathering is a form of chemical weathering that affects jointed bedrock and results in the formation of concentric or spherical layers of highly decayed rock within weathered bedrock that is known as saprolite. When saprolite is exposed by physical erosion these concentric layers peel (spall) off as concentric shells much like the layers of a peeled onion. Within saprolite spheroidal weathering often creates rounded boulders known as corestones or woolsack of relatively unweathered rock. Spheroida…

The definition here does not seem to make the important difference between erosion & weathering clear. If my A-level knowledge is correct doesn’t Weathering occur ‘in situ’ (without movement) and Erosion occur with some form of movement involved? –Albert 19:37 16 July 2006 (UTC) Yup. Reread the first line which says essentially the same thing.
