More details on the methods and data used in this study as well as five additional figures are provided below. ADDITIONAL DETAILS ON METHODS Mechanisms for calculating denudation rates using 10 BeOCTOPUS is a dataset that has calculated denudation rates based on in-situ Beryllium 10 isotope ( 10 Be) for over 4,000 river basins, spanning various tectonic and climatic environments (Codilean et al., 2018).10 Be, having a half-life of 1.39 × 10 6 years, is a kind of cosmogenic radionuclides (CRN) generated in the Earth's atmosphere and then falls out onto the ground.The 10 Be concentration in the sediments is highly
