GEOG 2051 Chapter : Material Strength Monday Feb 27 2011
Document Summary
9:45 am: cohesion, when you squeeze wet clay and it stays this is cohesion, things with clay have cohesion, sand has internal friction, different sand grains. With the more angular the grain comes more friction: the angle of repose is dependent on the degree of internal friction. Slope stability = shear strength over shear stress . Frozen ground: solifluction - soil is completely saturated, around the glacier, permafrost- ground is permanently frozen. Landrofms: patterned ground- when permafrost thaws and leaves patterned ground.
