Document Summary
Movement of downward because gravity, of soil, regality, or bedrock. Spontaneous: because it can move by itself, just from gravity. Soil: unconsolidated, naturally occurring to be considered soil must be. Two types of it: residual or transported: residual: when it forms from the bedrock below it, transported: rock fragmented in one place, and then got moved and deposited in another place. If luid agent transported: alluvium: streams, etc. Soil and regality can be more easily moved/transported to somewhere else: so more afected by mass wasing. Slide: when moving, top and botom material move at about same rate. Because of this very litle deformaion (change in shape) Surface over which material is moving: example: landslide. Rapid slide of large mass of bedrock or regolith. Sudden rock failure (physically weathered rock gives way), When you have a bend in a stream, it moves faster, and erodes bank.
