Sometimes called critical angle of repose, angle of repose refers to the maximum slop of a hill or plane before granular material would begin to roll down.
A high angle of repose can indicate granules that are sticky or a hill/slope made of something that is not very easy to roll down for some reason.
Irregular, angular gravel would likely have the greatest angle of repose since the pieces would easily interlock and would require more of a steep slope to break free and begin to fall down.
Angle of repose typically increases when the friction coefficient increases. The more friction between two objects the harder it would be for it to begin to simply roll or fall down.
