PURPOSE: How to read a topographic map, and how to find out things like the steepest parts and the gentle parts of land structures.

VOCABULARY: Contour lines: these lines connect points having the same elevation above sea level.
Contour intervals: The difference in elevation between two consecutive contour lines.
Relief: Difference in elevation between the highest and lowest points on a map.
QUESTIONS: 1. 136.5
2. South
3. 32
4. 199-0=199ft.
5. Contour lines and the flow of the rivers direction.
