* Gravity: Steeper slopes have a stronger gravitational pull on water and soil, causing them to move downhill faster.
* Water Flow: Water flowing down a steep slope has more kinetic energy, leading to increased erosion by scouring and transporting soil particles.
* Surface Runoff: On steeper slopes, rainwater has less time to infiltrate the ground, resulting in more surface runoff which can erode soil.
* Reduced Vegetation: Steep slopes often have less vegetation cover, which normally helps bind soil and slow down water flow.
However, there are exceptions:
* Very steep slopes may be relatively stable due to a lack of loose material to erode.
* Slopes with high vegetation cover can mitigate erosion even on steep terrain.
* Rockier slopes may erode more slowly than slopes composed of softer materials.
In general, though, a higher slope increases the potential for erosion.
