  15. M/P Weathering Chemical Weathering or Ice Wedging

  16. M/P Weathering Chemical Weathering or The iron in the soil is rusting (changing)

  17. M/P Weathering Chemical Weathering or Tree roots expanding

  18. M/P Weathering Chemical Weathering or The iron nails are rusting (changing)

  19. M/P Weathering Chemical Weathering or “Dust Bowl” Wind weathering and erosion
