On the opposite side of the stream, the water will be less turbulent. 7. a side of a mountain or building that is high and very steep. The mass movement process, also sometimes called mass wasting, occurs when soil and rock move down a slope under the force of gravity. Man-made steepening both undercuts the slope and sets up vibrations which may loosen rocks or soil. A slope which declines in steepness with movement downslope, also known as a waning slope.

Alluvium: rock particles (clay, silt, sand and gravel) deposited by a river. Hydrologic Characteristic & Heavy rains can saturate regolith reducing grain to grain contact and reducing the angle of repose, thus triggering a mass-wasting event. Entirely ertical sea walls experience the full violence of waves crashing against them, and are vulnerable to undercutting. Favorite Answer. Claessens et al. Christmas Island - Geography. Attrition: The particles are knocked about as they are transported, and they gradually become more rounded and reduced in size..
