  • 3.  
  • 4.  
  • 5.                            1:250,000 scale, 1 inch represents about 4 miles                            1:100,000 scale, 1 inch represents about 1.6 miles                            7.5 minute 1:24,000 scale, 1 inch represents 2,000 feet

  • 8. Contour line: line that connects points of the same elevation Elevation: height above sea level
  • 9.  
  • 10. Contour interval: shows the same change in elevation from contour line to contour line (represented by a number) Index contour: typically every 5th contour line, usually bolder or darker and it will have a number
  • 11.  
  • 12. 75 50
  • 13. 1400 1450
  • 14. The slope of land is shown by the closeness of the contour lines. Lines close together: steep slope; lines far apart; gentle slope
  • 15.  
  • 16. Full circle : shows the top of a hill, highest point; called the “summit” Often an “X” represents the actual elevation at that point
  • 17.  
  • 18. Full circle with short lines in it (hachures) represents a “depression” (downward change in elevation)
  • 19.
