Web1.8 Weathering The process in which rocks and soils lose their strength due to the modifications in physical, chemical, and mechanical properties by external agents such as water, wind, temperature change, etc. is known as weathering. Weathering significantly reduces the shear strength of the soil. Webparticularly long-slow drenching rain, the mountain slopes become saturated. The added weight induces rock falls, landslides, and other forms of mass movement of material down slope. Even though rain falls infrequently in the desert, when it does rain large quantities of sediment move down slope

For example, physical erosion can affect silicate weathering rates by modulating the supply of fresh reactive minerals (e.g., Stallard and Edmond, 1983; Calmels et al., 2007 ). Additionally, precipitation (and in turn runoff ...

WebWhen the force of gravity acting on a slope exceeds the resisting forces of a slope, the slope will fail and a landslide occurs. External factors can lead to landslides happening, including: heavy rainfall leading to saturation of the ground; erosion of the base of a slope ; changes to the material’s strength through weathering WebPhysical weathering, also called mechanical weathering, is a process that causes the disintegration of rocks, mineral, and soils without chemical change. The primary process in physical weathering is abrasion (the process by which clasts and other particles are reduced in size). Physical weathering can occur due to temperature, pressure, frost ...
