WebJan 1, 2014 · Rates of erosion vary greatly, depending on rock type, exposure, tidal position, and type and number of organisms. On coastal limestones, rates of surface lowering are about 1 mm/yr, but much higher rates—5-20 mm/yr—have been measured where species of sponges, molluscs, and echinoids are present. WebCyr et al. (2010) collected quartz sediment from streams draining landscapes with a variety of uplift rates. Although there was considerable scatter in the data reflecting stochastic erosional processes, the average erosion rate and the average uplift rate agree remarkably well in any given area.
