  4. Rates of Soil Erosion • By Water • Before the appearance of humans 9B netrictns of soil are transported by rivers to the sea…now 24B metric tons. • By Wind • Difficult to measure or estimate.

  5. Problems Associated to Erosion • Sedimentation • Chemical Pollution • Clogging and Flooding • Algal Bloom • Agricultural Problems

  6. Controlling Soil Erosion • Planting rows of trees called windbreaks • Terracing hillsides • Plowing along the contours of hills • Rotating crops

  7. Positive Results of Erosion • Creation of Ore Deposits • Secondary enrichment • Primary enrichment
