When the African-South American separation modified continental erosion

Land masses outside mountain ranges account for more than 60% of the world’s landmass. Despite their low relief and erosion, they make a significant contribution to the flow of sediments exported to the ocean. However, unlike mountain ranges, their export capacity has rarely been studied and has never been fully quantified. This constitutes a major bias in global erosion budgets, which are fundamental to understanding the links between climate, landforms and biogeochemical cycles on a global scale.
