  11. SWBAT . . . . . . interpret topographic maps.

  12. This is a “Mercator projection”. This one happens to be color coded by elevation On a Mercator projection, Greenland looks as wide as South America

  13. These are more realistic relative sizes for Greenland and South America. Greenland’s not quite as wide as South America, is it? Look on a globe if you don’t believe me. South America Greenland

  14. Robinson projection: less polar distortion than a Mercator projection, but still stretched a lot near the poles.

  15. Red lines are highways What are the red lines?

  16. What’s this symbol?. An AIRPORT!

  17. What are all the squiggley lines curving all over the place? contour lines

  18. What’s this? and this? and this? HILLTOPS or MOUNTAIN PEAKS

  19. Can you see the hash marks pointing inward? Those marks point downhill, often toward a lake or a pond.

  20. This is a pit. It might even be a volcanic crater. This is a hilltop

  21. Pass out the Topographic Map Analysis Worksheet • The squiggly lines are called . . . . . . contour lines

  22. Topographic Map Analysis Worksheet 2. The numbers found on some of the lines indicate . . . . . . elevation Note that the scale is in metric units, so the elevations are in meters. = altitude = height above sea level

  23. Topographic Map Analysis Worksheet 3. What does it mean when the lines are all close together? . . . A steep slope, maybe even a cliff.

  24. Topographic Map Analysis Worksheet 4. What does it mean when the lines are spread far apart? . . . A gentle slope, maybe even terrain you would call “flat”

  25. Topographic Map Analysis Worksheet 5. Where on the map do you think streams would flow during the rainy season or in the spring when snow melts? . . . Look for the parallel “V’s” that point uphill.

  26. Topographic Map Analysis Worksheet FLAT FLAT 6. Where are the flat areas? FLAT . . . wherever the lines are far apart FLAT FLAT FLAT FLAT FLAT FLAT

  27. Topographic Map Analysis Worksheet FLAT FLAT 7. Where are the cliffs? FLAT . . . wherever the lines are close together FLAT FLAT FLAT FLAT FLAT FLAT
