Document Summary

Causes (effects on frictional or gravitational force: factors controlling mass movement, gravity/slope steepness: items that are tangent/parallel to the surface when it moves downhill will resist friction. When gravity tangential to the surface is greater than the friction, this will cause movement of sediment: sediment type, angle of repose: the maximum steepness of loose material, assuming that it is dry. October 14, 2015: lack of vegetation can cause major fires and landslides, external shaking: movement of material lowers the force of friction as materials are jarred by the shaking, caused by: earthquakes, explosions, etc. Trees that have curved trunks: trees will grow vertically over time after slanting because trees like to grow upwards: road cracks. Leaning power poles: creep: unconsolidated, fluid that is very slow, debris flow: consolidated, wet fluid that is mixed with added water, which is similar to the flow of wet concrete, type of debris flow: lahars (created by.
