MASS WASTING PROCESSES AND LANDFORMS mass wasting gravitational movements of earth materials especially unconsolidated sediments and weathered rock water contributes to reduced strength of materials but is not involved as a geomorphic agent transitional between weathering and erosion, because it is closely related to the declining strength of weathering earth materials, but does not involve a transporting medium ( e.g. water, wind, ice) colluvium earth materials moved by gravity gravitation tendency for matter at the earth's surface to accelerate towards the center of the earth, given the small mass relative to the earth gives all mass above the earth's surface potential energy o PE = mgh o acceleration due to gravity (g) is constant (9.8 m sec -2 ) o therefore, for a unit mass PE is proportional to height or relief o slope gradient (h/d) is also an energy gradient governing the rate of conversion from potential to kinetic (1/2mv 2 ) energy o high geopotential energy is available for mass wasting in landscapes with large
