Competency Area 5: Soil conservation AEM

PO 44. Know how the topographic factors of slope and slope length affect soil erosion.

Erosion increases with increasing slope and slope length.

Steep slopes are more likely to become eroded, as evidenced by these hillsides.

The lighter areas have lost topsoil to erosion.
