What describes a convex slope?

A convex slope is characterized by its shape, where the slope bows outward. This configuration can lead to instability because as water runs down the slope, it can create additional erosion or slippage, particularly on the upper parts where the slope is steeper. The outward curvature means that the forces acting on materials below have a tendency to push them down and away, which contributes to a greater risk of landslides and other forms of erosion.

In contrast, types of slopes that are more stable, such as a concave slope or a flat area, do not display the same risks associated with outwardly bowed slopes. Therefore, the defining feature of a convex slope—the outward bowing—significantly impacts its stability and susceptibility to failure. Recognizing this characteristic is essential in landscape architecture and soil management, as it informs decisions about construction, vegetation management, and erosion control.
