what is mass movement
the movement of regolith downslope in response to gravity
slowest type of mass movement
soil creep
what happens in soil creep
gravity slowly pulls the regolith downslope
how can soil creep be determined
bent fences
broken telephone poles
trees that bend/curve
roads may crack
types of mass movement
slow
fast
medium
where does soli fluction occur
where there is ice and snow and vegetation cover is limited
how does soli fluction occur
soil saturated with melted snow becomes slippery and slides and moves slowly downslope
what does soli fluction involve
freeze thaw
what slope does earth flow occur in
5 degrees - 15 degrees
how does earthflow occur
soil becomes saturated and the regolith moves downslope. the flow ends in a lobe like mass.
where does mudflow occur
steeper hills
which is faster earthflow or mudflow
mudflow
Rapid movement
slides
