This process is known as mechanical weathering. The downward slope of the region combined with the melting permafrost underneath resulted in the movement of the rocks downward, or mass wasting, to ...

Mass wasting includes both gradual, infinitesimally slow soil creep on slopes and rapid, catastrophic mass movements, called landslides. Long trains of rock debris can form scree slopes ...

A geological event, mass wasting is the gravity-influenced movement of rock and soil down a slope. A gully is a landform created by erosion from running water, mass movement or both. The Sedongpu ...
