  1. Geomorphology Mr. Skirbst Earth Science Topic 27

  2. Geomorphology Geo – earth

  3. Geomorphology Geo – earth Morph – form

  4. Geomorphology 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)
