WebWeathering rates are a function of the rock type, slope (topography), structure, and the prevailing climate (Figs. 7.5–7.7). Rocks that are most resistant are composed of minerals that are relatively unaffected by chemical weathering. Quartz is a classic example which is unaffected by dissolution, hydrolysis and oxidation.
