What Role Does Friction Play in Abrasion?

šŸ’” The Answer

  • Abrasion is caused by friction from scuffing, scratching, wearing down.
  • Friction between moving particles and surfaces removes material.
  • In glaciers, friction from sliding ice abrades bedrock.
  • In rivers, particles scrape against bed and walls.
  • Wind-driven sand friction abrades rock surfaces.
  • Frictional forces convert kinetic energy into wear.
