Which of the following terms refers to the maximum angle of a stable slope formed by loose, unconsolidated granular material under the action of gravity?

💡 Solution & Explanation

The angle of repose represents the steepest inclination to which loose granular materials can be piled without undergoing gravitational sliding or slope failure. This physical property depends heavily on particle friction, size, and shape. Other parameters like the angle of dip measure structural geological features in rock strata rather than surface sediment stability. Engineering geography questions routinely apply this concept to civil construction and landslide susceptibility assessments.
