These may be convex, straight, or concave; the shape of a slope is an expression of the predominant processes acting on it.Convex slope elements are usually gentle, generally at the top of a slope, and formed by soil creep and rainsplash. The movement of the material is called creeping, sliding, flowing, toppling, and falling. JC Rivers. 0. This slower, gentler water is less capable of carrying the load or material being transported by the water, so it is a location of deposition.
