Short summary
Sediment generation on hillslopes and transport through river networks are complex processes that influence landscape evolution. In this study, we compiled sand from 766 river basins and measured its subtle radioactivity to unravel timelines of sediment routing around the world. With these data, we empirically confirm that sediment from large lowland basins in tectonically stable regions typically experiences long periods of burial, while sediment moves rapidly through small upland basins.
