The rain wears tiny particles off of rocks and carries them down a slope.
Rainfall, Water, Wind, Ice, and Gravity
after brief and heavy rainfall
Over-cultivation is the biggest cause of soil erosion in the Philippines. A secondary cause is the amount of rainfall the country receives.
Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams. Rivers - Rivers can create a significant amount of erosion over time. They break up particles along the river bottom and carry them downstream.
Water causes the soil to soften up and become slippery, causing landslides. In addition, excessive rainfall leads tobsuper-saturated soil, which cannot hold up against gravity. Gravity in one form or another is the main cause of landslides, and too much rainfall weakens the soil's sub-structure.
Soil erosion.
Erosion is worse when farms are in areas with high rainfall or severe drought.
heavy rainfall
Sheet erosion
When rainfall increases erosion increases, wearing away the mountains and cliffs and filling in the canyons with the products of erosion.
