Final answer:
The simplest and most obvious form of mass wasting is landslides. Landslides occur when gravity causes the movement of rocks, soil, and debris on slopes. There are several factors that can contribute to landslides.
Step-by-step explanation:
The simplest and most obvious form of mass wasting is landslides. Landslides occur when gravity causes the movement of rocks, soil, and debris on slopes. There are several factors that can contribute to landslides, such as oversteepened slopes, saturation by snowmelt or heavy rains, earthquakes, volcanic eruptions, and excess weight from accumulated rain or snow.
