Which mechanism causes increased sediment load in streams after forest wildfires?

💡 Explanation

Wildfires cause decreased aggregate soil stability because organic matter binding soil particles burns away, weakening the soil structure. This occurs through accelerated weathering due to heat exposure, therefore increasing soil erosion and sediment runoff rather than directly by evapotranspiration or precipitation.
