Across
  1. 2. movement of loose surface material (regolith) downslope due to gravity
  2. 3. roots hold soil together, removing it causes more movement
  3. 7. fast flow of saturated soil and water after heavy rain
  4. 11. major mudslide in 2016 due to heavy rain
  5. 15. road cutting or quarrying undercuts slopes, causes collapse
  6. 16. more water makes regolith heavier and slippery, increases movement
  7. 17. steeper slopes cause faster movement
  8. 18. very slow movement of soil downslope, less than 1 cm/year
  9. 19. fast movement of waterlogged peat, usually in upland areas
  10. 21. area in Sri Lanka where mudslide happened
  11. 22. trees curve as soil creeps under them
Down
  1. 1. blocked roads, polluted rivers, crop damage
  2. 4. 134 dead, 60 homes buried, 350,000 people displaced
  3. 5. small ridges on a slope formed by soil creep
  4. 6. example of landslide in Kerry, 2011 — destroyed road and bridge
  5. 8. telephone poles leaning downslope due to soil creep
  6. 9. caused by slowly shifting ground beneath
  7. 10. volcanic mudflow made of ash, soil, water, snow — flows after eruptions
  8. 12. fast movement of rock/soil downslope caused by rain, earthquakes, cutting
  9. 13. the force pulling materials downhill
  10. 14. loose weathered rock and soil
  11. 20. partially decayed plant matter found in bogs
