6. What is biological weathering

  • plants breaking down the rocks
  • rocks being crushed
  • animals decomposed in the rocks

7. What animal... has a large fat hump, large water supply, large padded feet, hard mouth meaning it can eat cactus

  • Kangaroo Rat
  • Fennec Fox
  • Camel
  • Jack Rabbit

8. What type of plant is this... Long roots, grows by salt pans

  • Phreatophytes (Mesquite)
  • Ephemerals (Verbena)
  • Halophytes (Prickle Weed)
  • Succulents (Cacti)
  • Xerophytes (Creosote Bush)

9. What type of plant is this... Swollen stems, small Leafs, thick cuticles, sunken stomata

  • Xerophytes (Creosote Bush)
  • Phreatophytes (Mesquite)
  • Ephemerals (Verbena)
  • Succulents (Cacti)
  • Halophytes (Prickle Weed)

10. What is Abrasion

  • Wind blown particles crashing into the rock
  • Material rubbing together causing wearing away.
  • the entrainment and removal of loose material by the wind

11. what is surface creep

  • sand bouncing along the surface of the ground
  • material rolling along the ground
  • fine dust carried by the wind

12. what animal... cools exhale in nasal passage, gets its water from food and licks fur to keep cool

  • Jack Rabbit
  • Camel
  • Kangaroo Rat
  • Fennec Fox

13. What is this... high temperatures cause for the rocks to expand during the day and low temperature in the evening cause it to shrink meaning layers peal off.

  • salt crystal weathering
  • Isolation (onion skin weathering)
  • freeze thaw
  • wetting and drying

14. what is this... Water or liquid gets into cracks in the rock when the temperature decreases the water freezes and expands by around 10% this process is repeated and the rock begins to crack

  • Freeze Thaw
  • Isolation
  • Salt Weathering
  • Wetting and Drying

15. What type of plant is this... stores water, closed stomata during the day, spikes for protection

  • Succulents (Cacti)
  • Halophytes (Prickle Weed)
  • Xerophytes (Creosote Bush)
  • Ephemerals (Verbena)
  • Phreatophytes (Mesquite)

16. What type of plant is this... Remain as seeds, only germinate during rain, small shallow roots.

  • Phreatophytes (Mesquite)
  • Ephemerals (Verbena)
  • Halophytes (Prickle Weed)
  • Succulents (Cacti)
  • Xerophytes (Creosote Bush)

17. what is suspension

  • fine dust carried by the wind.
  • sand moving in a series of hops
  • material rolling along the ground

18. What is this... repeated change in the temperature and weathering can cause for break down to occur

  • Freeze Thaw
  • Isolation
  • Wetting and drying
  • Salt Crystal Weathering

19. What is this... high temperatures cause for all moisture to be drawn out of the rock including salt, this dries out and crystals form causing crack to form and the rock begins to disintegrate

  • wetting and drying
  • Salt Crystal weathering
  • isolation
  • Freeze thaw

20. What is Saltation

  • sand bouncing along the surface of the ground
  • fine dust carried by the wind
  • material rolling along the ground
