In transport-limited processes, the rate of soil and rock transport limits the delivery of sediment to streams. In other words, the supply of sediment exceeds the capacity to remove it, and transport processes and their spatial variation dictate hillslope form. Soil creep, through-wash, rainflow, rainsplash, and rillwash are all hillslope processes limited by transporting capacity. On supply-limited or weathering-limited hillslopes, the rate of sediment production by weathering and erosional detachment through overland flow and mass movement limits the delivery of sediment to streams.

In other words, weathering and erosional processes dictate hillslope form. Leaching of solutes, landsliding, debris avalanches, debris flows, and rockfall are all hillslope processes limited by sediment supply. High temperatures contribute to slope instability by enhancing the thermal breakdown of rock, decreasing the viscosity of groundwater i. Warm conditions can also cause increased evaporation, leading to drier soils and more stable conditions in deeper soils, especially in summer.

Finally, warming can intensify the cycling between wet and dry periods, which may act to widen gaps in rock and soil, contributing to a decrease in slope stability. Heavy rain events reduce slope stability by rapidly raising the water table or groundwater elevation and by enhancing water drainage through the soil to lower layers. In addition, intense rainfall can erode surface sediments, and higher streamflow during these events can transport more sediment downstream.

Different patterns of rainfall will affect which slopes might be destabilized, and where erosion and sediment transport are most important. Wetter soils are heavier, can absorb less precipitation thus increasing runoff , and have greater lubrication among soil layers. Analysis from the landslides often indicates that the initial conditions of the soil prior to the triggering events are an important contributor to the mobility and, as a result, the severity of the landslide.

Higher snowlines can lead to exposure of unconsolidated erodible sediment, more ground surface erosion, greater soil saturation, and higher streamflows. Retreating glaciers uncover loose, unvegetated sediment that is vulnerable to mobilisation. Melting glaciers typically leave behind sediments that are then exposed to weather and erosion.

Large earthquakes can trigger widespread landsliding. In addition to causing extensive socioeconomic disruption, earthquake-induced landslides play a key role in the evolution of mountain landscapes, increasing sediment flux through the fluvial networ and contributing to net erosion rates. While earthquake ground shaking triggers near-instantaneous landsliding, some slopes do not fully fail and are weakened, resulting in elevated susceptibility of hillslopes to landsliding during postseismic rainfall and subsequent seismicity.

It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological. The process tends to be self-reinforcing: weathering weakens the rocks and makes them more permeable, so rendering them more vulnerable to removal by agents of erosion, and the removal of weathered products exposes more rock to weathering.

Living things have an influential role in weathering, attacking rocks and minerals through various biophysical and biochemical processes, most of which are not well understood. The weathered mantle or regolith is all the weathered material lying above the unaltered or fresh bedrock. It may include lumps of fresh bedrock. Often the weathered mantle or crust is differentiated into visible horizons and is called a weathering profile as shown in the figure below.

The weathering front separates fresh bedrock from the regolith. The regolith is divided into saprock, saprolite, and a mobile zone. The weathering front is the boundary between fresh and weathered rock. The layer immediately above the weathering front is sometimes called saprock , which represents the first stages of weathering. Above the saprock lies saprolite ; this is more weathered than saprock but still retains most of the structures found in the parent bedrock.
