2.  What are landforms?  How are they formed?

3. FORCES CAUSING LANDFORMS ENDOGENICDIASTROPHIC EPIOROGENIC UPLIFT & SUBMERGENC E (CONTINENT BUILDING FORCES) OROGENIC (MOUNTAIN MAKING FORCES) SUDDEN CONSTRUCTIVE FORCES VOLCANIC ERUPTIONS EARTHQUAKESEXOGENIC ALLUVIAL AND EROSIONAL PLAINS

4. LANDFORMS AND THEIR TYPES MOUNTAINS PLATEAUS PLAINS

5. TYPES OF MOUNTAINS FOLD MOUNTAINS BLOCK MOUNTAINS VOLCANIC MOUNTAINS

6. FOLD MOUNTAINS  How are fold mountains formed?

7. FEATURES OF FOLD MOUNTAINS 1. IRREGULAR FOLDS IN FOLD MOUNTAINS DUE TO UNEQUAL PRESSURE

8.  What does this image show

9.  Which type of rocks have this feature?  How are these rocks formed?

10. FEATURES OF FOLD MOUNTAINS FEATURE 2: MOST OF THESE MOUNTAINS ARE CONSTITUTED OF SEDIMENTARY ROCKS FORMED DUE TO DEPOSITION AND CONSOLIDATION OF SEDIMENTS IN SHALLOW OCEANS

11. FEATURES OF FOLD MOUNTAINS 3. FOLD MOUNTAINS HAVE GREATER LENGTH BUT COMPARATIVELY SMALL WIDTH

12. FEATURES OF FOLD MOUNTAINS FEATURE IV: MOST FOLD MOUNTAINS ARE FOUND ON THE MARGINS OF CONTINENTS FEATURE V : FOLD MOUNTAINS ARE ASSOCIATED WITH VOLCANIC ACTIVITY AND HAS MANY ACTIVE VOLCANOES

13. VOLCANIC MOUNTAINS

14. BLOCK MOUNTAINS  How are block mountains formed

15. BLOCK MOUNTAINS

16. IDENTIFY THIS PHYSICAL FEATURE

17. PLATEAUS 1. INTERMONTANE PLATEAU 2.PIEDMONT PLATEAU 3.VOLCANIC PLATEAUS 4.UPLIFTED PLATEAU

18. INTERMONTANE PLATEAU  Highest and most extensive  Surrounded by hills and mountains.

19. INTERMONTANE PLATEAU

20. TIBET PLATEAU

21. LOCATION OF TIBET PLATEAU

22. PIEDMONT PLATEAUS  Mountain ranges on one side and plains on one side.  The part facing the plain is steep.

23. PEIDMONT PLATEAU

25. VOLCANIC PLATEAU

26. COLUMBIAN PLATEAU

27. LOCATION OF COLOMBIAN PLATEAU

28. UPLIFTED PLATEAU

29. CHOTA NAGPUR PLATEAU

30. PLAINS  What are Plains

31. PLAINS

32. TYPES OF PLAINS PLAINS STRUCTURALEROSIONAL DEPOSITIONA L

33. STRUCTURAL PLAINS  Formed due to uplift or subsidence of land

34. LOCATION OF THE GREAT PLAINS OF USA

35. ERROSIONAL PLAINS  These plains are formed by agents of erosion like  River  Wind  Chemical weathering

36. TYPES OF EROSIONAL PLAINS  EROSIONAL PLAINS Peneplains Glacial erosion Wind eroded Karst plain

37. PENEPLAINS  Landscapes in which almost all hills have been worn down as a result of erosion  The word peneplains means almost a plain

38. PENEPLAINS

39. LORRAINE PLAIN IN FRANCE

40. LOCATION OF LORRAINE PLAIN

41. GLACIAL EROSION  These plains have rounded peaks and worn down ice scoured shield lands  Due to the action of the glacier the area gets worn down and the height is reduced.

42. GLACIAL EROSION

43. PLAINS OF GLACIAL EROSION

44. WIND ERODED PLAINS

45. KARST PLAINS

46.  Due to chemical weathering the area gets eroded and produces undulating topography.  This type of features are mostly found in limestone landscapes where chemical weathering takes place.

47. DEPOSITIONAL PLAINS  These plains are caused due the deposition of various agents such as  River  Wind  Sea

48. RIVER DEPOSITION

49. RIVER DEPOSITIONAL PLAINS

50. GANGA ALUVIAL PLAIN

51. WIND DEPOSITION PLAIN

52. MARINE DEPOSITION PLAIN
