Clues

  • Biological weathering involves both mechanical impacts such as the growth of roots, and chemical impacts such as the release of organic acids. (10, 10)
  • In areas of calcareous rock, material is carried in solution as the dissolved load. (9, 8)
  • Loose, broken material that is often easily eroded. (14, 5)
  • Pebbles are shunted along the bed as the tracted (bed) load. (9, 8)
  • Slow movement. On flat surfaces, raindrops compact the soil and dislodge particles equally in all directions. On steep slopes this causes erosion downslope. (4, 6, 7)
  • solid rocks or sediments that have been bonded together by a sedimentary cement. (12, 5)
  • The removal of chemical ions, especially calcium. It is a form of erosion especially effective on chalk and limestone. (7, 8)
  • The spiraling flow motion that occurs in a meander. (10, 4)
  • The wearing away of the bed and bank by the load carried by a river. (7, 8)
  • The wearing away of the load carried by a river. It creates smaller, rounder particles. (7, 9)
