Quizplus · Accepted Answer

Dry gravel is the best choice for a stable slope with an angle of repose of 35 degrees. The angle of repose is the maximum slope angle at which the material on the slope is stable and will not slide. Dry gravel has a higher angle of repose than saturated sand or gravel, which makes it a better choice for stability. Saturated sand and gravel are more likely to be affected by groundwater or heavy rainfall, which can increase the risk of landslides.
