2. Geomorphology
Geo – earth

3. Geomorphology
Geo – earth Morph – form

4. Geo – earth Morph – form Geomorphology – “earth forms” or “landforms”

5. Geomorphology
Topography

6. Geomorphology
Topography the shape of Earth’s surface

7. Geomorphology
Topography the shape of Earth’s surface it’s determined by landforms

8. Geomorphology
3 Main Landform Types:

9. Geomorphology
3 Main Landform Types:
Mountain – high elevations

10. Geomorphology 3 Main Landform Types: Mountain – high elevations
Plain – flat, close to sealevel

11. Geomorphology 3 Main Landform Types: Mountain – high elevations
Plain – flat, close to sealevel
Plateau – flat, high elevation

12. Maps

13. Maps
Meridian (longitude)

14. Maps
Meridian (longitude) lines from North to South poles

15. Maps
Meridian (longitude) lines from North to South poles measure distances East / West

16. Maps
Meridian (longitude) lines from North to South poles measure distances East / West measured in 180o from Prime

17. Maps
Meridian (longitude) lines from North to South poles measure distances East / West measured in 180o from Prime measured as E or W longitude

18. Maps
Parallel (latitude)

19. Maps
Parallel (latitude) lines parallel to Equator

20. Maps
Parallel (latitude) lines parallel to Equator measures distance North/South

21. Maps
Parallel (latitude) lines parallel to Equator measures distance North/South measured from 0 to 90o

22. Maps
Parallel (latitude) lines parallel to Equator measures distance North/South measured from 0 to 90o measured as North/South latitude

23. Topographic Maps

24. Topographic Maps
Show the relief of the land

25. Topographic Maps
Show the relief of the land Relief (topography) shown with contour lines

26. Topographic Maps
Show the relief of the land Relief (topography) shown with contour lines Contour lines – lines of equal elevation

27. Local Landforms
Rivers, streams, drainage areas

28. Local Landforms
Rivers, streams, drainage areas Mountains, hills, mounds

29. Local Landforms
Rivers, streams, drainage areas Mountains, hills, mounds Valleys, depressions, quarries

30. Local Landforms
Rivers, streams, drainage areas Mountains, hills, mounds Valleys, depressions, quarries Ponds, swamps

31. Local Landforms
Rivers, streams, drainage areas Mountains, hills, mounds Valleys, depressions, quarries Ponds, swamps, wetlands Flood plains, steep slopes

32. Interpreting Topographic Maps
Basic Rules: Contour lines …..
… never cross

33. Interpreting Topographic Maps
Basic Rules: Contour lines …..
… never cross
… close together = steep slope

34. Interpreting Topographic Maps
Basic Rules: Contour lines …..
… never cross
… close together = steep slope
… far apart = gentle slope

35. Interpreting Topographic Maps
Basic Rules: Contour lines …..
… never cross
… close together = steep slope
… far apart = gentle slope
… form loops around hills / holes

36. Interpreting Topographic Maps
Basic Rules: Contour lines …..
… never cross
… close together = steep slope
… far apart = gentle slope
… form loops around hills / holes
… form “V’s” in valleys and point
upstream (or uphill)
