15 Topography Associated With Inclined Strata
(Inclined = tilted) (Strata = layers)

16 Cuesta

17 Cuesta

18 Practice

20 Scarp Retreat

21 Homoclinal Ridge

22 Hogsback

23 Topography Associated With Igneous Rocks

24 Underground Igneous Features

25 Batholith: Paarl Rock

26 Tor

27 Tor Development

28 Tor Development Mechanical, chemical and biological weathering exploits the weaknesses in the underlying igneous dome As the landscape becomes denuded, the core rocks are exposed Exposure to surface weathering, leaves the core rocks rounded and in block formation

29 Exercise 1 Landforms Exercise

30 Exercise 2

31 Mass Wasting The movement of material down a slope under the influence of gravity

32 Soil Creep

33 Soil Creep

34 Terracettes and Soil Erosion

35 Rockfalls

36 Rock Avalanche

37 Mudslide/ Mudflow

38 Mudslide

42 Turtle Mountain

43 Landslides

44 Activity Make a list of the different forms of mass wasting comparing:
Speed at which it occurs Moisture content Likely damage

45 Human responses to mass wasting

46 Risk Factors
