Ch6: Mass movement

• Factors affecting mass movement:

  • Gradient - the steepness of the slope. A steeper slope means the regolith moves faster.
  • Water content - water makes regolith heavier. Heavier regolith moves downhill faster. Water also acts as a lubricant.
  • Vegetation - grass and shrubs protect the soil from weathering and erosion. The roots of a tree bind the soil together, preventing soil erosion.
