Raindrop-formed ‘sandballs’ that erode hillsides tenfold High-speed laboratory images capture two distinct “sandball” shapes formed when raindrops strike dry, sloped sand and roll downhill.

(Bottom) Donut-shaped sandballs, which densify into rigid, wheel-like structures with a hollow center, enabling far more efficient sediment transport than splash erosion alone.(Image: Daisuke Noto) Raindrop-formed ‘sandballs’ that erode hillsides tenfold Penn geophysicists and colleagues have uncovered Earth-sculpting processes that result from the formation of snowball-like aggregates they call “sandballs.” Their findings provide fundamental insights into erosion and will broaden scientific understandings of landscape change, soil loss, and agriculture. 3 min. read
