The stratigraphic record for the period 470–460 Myr (Darriwilian) also shows evidence for mass wasting (downslope movement of sediment and rock) at the contemporaneous continental margins on a ...

Erosion: the movement of loose rock or soil as a result of ice, wind or water. Glacier: a large, slow-moving mass of ice and compacted snow that travels over land. Geology: the study of the structure ...

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. Damning the Siang ...

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 ...
