  4. Things you find on a Contour or Topo Map: • Contour Lines that show elevation • Compass directions to show N, S, E, W • A scale for distances • Latitude and Longitude • A Key to show different features and locations • Colors: • Blue = Water White = Bedrock • Brown = Contour Lines Red = Roads • Green = Vegetation Black = Names • Title and Location of the area the map is from • Magnetic Declination: Mrs. Degl

  5. Things to know about Contour Maps: • Contour Interval means “what every line is worth”. • The rule of the Contour V’s • Streams and rivers flow opposite to the point of the V that is • formed when a contour line crosses them. • Close contour lines means that there is a steep slope. • Contour lines that are far apart mean that the land is flatter. • Gradient means slope. • Bulls eyes represent hills or mountains. • Each line represents a different elevation in feet or meters. • Places on the same contour line are at the same elevation. • A Profile is a side view or real representation of the topography • of an area.
