Plot illustrating the different methods available for quantifying erosion rates. It also shows the range of temporal and spatial scales over which these methods are applicable. Any of these methods can in principle be used to quantify erosion over geomorphological timescales but cosmogenic nuclides are the most suitable because: (1) are produced at shallow depths and so unlike low-temperature thermochronometers are highly sensitive to changes in surface morphology, and (2) accumulate over longer timescales and so unlike historical methods (such as using sediment volume data) are not prone to anthropogenic disturbance.
