Short summary
The critical zone near the surface of the Earth is where geologic substrate, erosion, climate, and life meet and interact. This study focuses on mechanisms of physical weathering that produce loose sediment and make it available for transport. We show that the sediment export from a monitored catchment in the French Alps is modulated by frost-weathering processes and is therefore sensitive to complex modifications in a warming climate.
