Topographic Maps
PART A: Write true if the statement is true. If the statement is false, change the underlined term to make it true.
1. A map that uses contour lines to show elevation is called a topographic map. 2. Every point on a single contour line is at a different elevation. 3. When contour lines are close together, the land has a gentle slope. 4. The difference in elevation between one contour line and the next is called the contour interval. 5. When contour lines cross a river, they form a “V” that always points down‐stream. 6. The ratio of distance on a map compared to the actual distance on Earth is known as the map scale. 7. On a topographic map where one contour line is 20 m and the next is 30 m, the contour interval is 50 m. PART B: Use the topographic map below to answer the following questions.
1) What is the contour interval? _________ 2) How high above sea level is Falcon Mountain? _______________ 3) How high above sea level is Globe Mountain? _______________ 4) What compass direction does Mill River flow towards? _________ 5) What compass direction does North Stream flow towards? _________ 6) What is the elevation of the mouth of Mill River? _________ 7) Is the East slope or West slope of Globe Mountain steeper? _________ 8) What is the scale of this map? ___________________________ 9) About how long is Mill River? Give your answer in meters. __________ Concepts and Challenges in Earth Science, Teacher’s Resources CD-ROM
