Angle of Repose
the steepest angle at which loose material remains stationary without sliding downslopes
Fall
a type of movement common to mass-wasting processes that refers to the free falling of detached individual pieces of any size
Flow
a type of movement common to mass-wasting processes in which water saturated material moves downslope as a viscous fluid
Horizon
a layer in a soil profile
Internal Processess
derive energy from the Earth's interior
Permafrost
permanently frozen layer of soil beneath the surface of the ground
Secondary Enrichment
thje concentration of minor amounts of metals that are scattered through unweathered rock into economically valuable concentrations by weathering processes
Slide
a movement common to mass wating processes in which the material moving downslope remains fairly coherent and moves along a well defined surface
