Cards in this set: Term Mass wasting Definition downslope movement of rock materials by gravitational forces without being carried within, on, or under any other medium Term Gravity Definition factors affecting slope stability; force of attraction between two bodies Term Cohesion Definition factor affecting slope: strength of a material derived from properties other than intergrangular friction Term Friction Definition factor affecting slope; force that resisits the motion or tendency of motion between two bodies or between a body and a medium Term Angle of repose Definition angle up to which loose uncosolidated materials will be at rest; when angle is exceeded, materials will begin to slide and roll downslope Term Creep Definition the slow, continuous movement of regolith downslope under influnece of gravity (mass wasting) Term Earthflow Definition type of mass wasting in whcih soil and loose rock move over a laterally confined, basal shear zone, oriented roughly paralle to the ground surface, with litte rotation of the sliding materials Term Slump Definition mass wasting; shearing and rotation of regolith or rock along curved concave-upward , slip surfaces with and axis of motion parallel to slope face Term Rock falls Definition free fall of rock fragments newly detached from very steep surface Term Talus Definition accumulation of rock fragments at base of a steep slope such as a cliff or road cutt Term Rock slides Definition sudden and rapid movement of rock down surface
