Convex slopes are associated with regions of tension and are more likely to be trigger points. Concave sections of small slopes can sometimes support the steeper section above.

A convex slope is a slope that steepens as it descends. It is also known as a convexity, roll, or rollover. Avalanches often fracture at or just below the roll in the slope.
