Earth Science Name_____________________________ Chapter 3 Period_____________________________ Lab Date______________________________ __________________________________________________________________________________ Exploring a Topographic Map Geneva Quadrangle Use the topographic map of the Geneva Quadrangle to complete the questions below. (0.5 points each, 15 points total) Name and North _______________ 1. What is the name of this quadrangle, and the date it was published? _______________ 2. Which way is north on the map (top, bottom, left, right)? Latitude and Longitude 3. The latitude in this map area is given on the right and left edges of the map in minutes and seconds, and in the corners in degrees, minutes, and seconds. _______________ What is the latitude of the northern boundary of this map? _______________ What is the latitude of the southern boundary of this map? _______________ How many total minutes of latitude does this map cover? 4. The longitude in this map area is given on the top and bottom edges of the map in minutes and seconds, and in the corners in degrees, minutes, and seconds. _______________ What is the longitude of the eastern boundary of this map? _______________ What is the longitude of the western boundary of this map? _______________ How many total minutes of longitude does this map cover? _______________ 5. Give the latitude and longitude of the southwest corner of this map. _______________ 6. Give the approximate latitude and longitude of Geneva High School. Scale and Distance _______________ 7. What is the fractional scale of this map? _______________ Given the scale from the previous question, answer this. If from the doors of the high school to the far end of the Burgess parking lot is 1 inch on the map, how many inches is it in reality? _______________ 8. How wide is Geneva from Kirk to Randall in miles? (Use the graphic scale of this map, to find how many miles (to the nearest tenth of a mile, example: 2.3 miles) is it from Kirk Road to Randall Road. Use the straight line distance from Kirk to Randall across the center of the high school.) _______________ 9. To the nearest whole mile, approximately how many miles of the Fox River is shown on this map? Symbols and Color _______________ 10. Find Harrison Street School on the map. Draw the symbol used to represent it. _______________ 11. Find the Pratts Wayne Woods County Forest Preserve in the northeast corner of the map. Draw and identify the map symbol that represents some of the ground around the lake near the 57’30” N latitude mark on the eastern edge of the map. _______________ 12. What does the color red represent on the map? _______________ 13. What does the color pink represent on the map? _______________ 14. What does the color black represent on the map? _______________ 15. What does the color brown represent on the map? Contour Lines and Elevation _______________ 16. What is the contour interval of this map? _______________ 17. What is the approximate elevation of the southern tip of Burgess Field? _______________ 18. What is the exact elevation given by the benchmark along IL 31 on the northern tip of Wheeler Park? _______________ 19. What is the approximate elevation of the Fox River directly east of that benchmark? Finding Slope _______________ 20. What is the approximate elevation of the Fox River at the gaging station near Old Mill Park just north of the IL 38 Bridge? _______________ 21. There is another gaging station near the northern border of the map on the Fox River. What is the approximate elevation of that station? _______________ 22. What is the difference in elevation between those two points (in feet)? _______________ 23. Within a thousand feet, how far apart are those two gaging stations (in feet!)? _______________ 24. Lets find the slope of the land under the Fox River in this area. To find the slope between any two points on a map, all you need to do is simply divide their difference in elevation (which you found in question 23), and the distance between them (which you found in question 24). Follow the formula below and calculate the slope between the two gaging stations at the north and south ends of the Fox River. Change in elevation (rise) #23 Slope = --------------------------------- = ------- = -----------------------Distance between (run) #24 25. The fastest rivers, like the Colorado as it rages through the Rocky Mountains, flow over a land sloping at about 0.5. Some of the slowest rivers like the old Mississippi flow over land sloping at about 0.002. Describe how the slope of the land under the Fox River compares to the slope of the land under some of the fastest and slowest moving rivers.
