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: 1.Mountain – high elevations

10 Geomorphology 3 Main Landform Types: 1.Mountain – high elevations 2.Plain – flat, close to sealevel

11 Geomorphology 3 Main Landform Types: 1.Mountain – high elevations 2.Plain – flat, close to sealevel 3.Plateau – flat, high elevation

12 Maps

13 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 180 o from Prime

17 Maps Meridian (longitude) lines from North to South poles measure distances East / West measured in 180 o 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 90 o

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

23 Topographic Maps

24 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 ….. 1.… never cross

33 Interpreting Topographic Maps Basic Rules: Contour lines ….. 1.… never cross 2.… close together = steep slope

34 Interpreting Topographic Maps Basic Rules: Contour lines ….. 1.… never cross 2.… close together = steep slope 3.… far apart = gentle slope

35 Interpreting Topographic Maps Basic Rules: Contour lines ….. 1.… never cross 2.… close together = steep slope 3.… far apart = gentle slope 4.… form loops around hills / holes

36 Interpreting Topographic Maps Basic Rules: Contour lines ….. 1.… never cross 2.… close together = steep slope 3.… far apart = gentle slope 4.… form loops around hills / holes 5.… form “V’s” in valleys and point upstream (or uphill)
