  1. Topographic Map: Key Concepts

  2. Contour maps show the following: The elevation of the land above sea level. “A bird’s eye view! Topographic Map: Key Concepts

  3. The connect points that are at the same elevation They never cross or touch They are imaginary lines They always connect and form a circle Rules of Contour Lines

  4. BENCHMARK: A benchmark is a place on a map where exact elevation is known. It is marked BM on a map. Parts of a Topographic Map

  5. MAP SCALE A map scale shows the distance on a map in relation to Earth. Parts of a Topographic Map

  6. MAP LEGEND A map legend explains the symbols used on a map. Parts of a Topographic Map

  7. CONTOUR INTERVAL A contour interval is the difference in elevation between two contour lines. Other Key Concepts

  8. When lines are close together, they represent a steep slope. When lines are spread apart, they represent a gradual slope. Other Key Concepts

  9. Dark Contour Lines: What do they mean?

  10. Hachure Lines: What do they mean?

  11. Blue Lines/Shapes: What do they mean?

  12. Brown Lines: What do they mean?

  13. Black Lines/Shapes: What do they mean?

  14. Green: What do they mean?

  15. Red What do they mean?

  16. Contour lines that cross water form a “V” that points UPSTREAM! Did you know?
