  1. Measuring Earth Notes: Pages 3 - 9 ©Mark Place, 2009-2010 www.LearnEarthScience.com

  2. Earth’s Spheres Information regarding Earth’s atmosphere can be found on page of the ESRTs

  3. Earth’s Spheres Information regarding Earth’s interior can be found on page of the ESRTs

  4. Earth’s Spheres Information regarding Earth’s hydrosphere can be found on page of the ESRTs

  5. Please answer the questions on Page 3 of your Notes

  6. Answers: 1. 4600°C, 1.2 million atmospheres (+/- 0.2) 2. oxygen 3. -90°C 4. 0°C 5. 12 km

  7. What is the purpose?

  8. Who uses topographic maps? the military miners police farmers

  9. When might someone use a topographic map? building homes plan a hiking trip landscaping road building

  10. Contour Interval? 25

  11. Contour Interval? 20 Elevation of "A"? 540 Elevation of "B"? 580

  12. Highest possible elevation? 619

  13. What do hachured lines show? areas of depression

  14. What are the rules concerning hachured lines? first hachured line has same elevation as previous contour line

  15. If north is at the top of the page, what direction is this river flowing? south

  16. Can a river flow north? yes!

  17. Name two ways that you can determine which way a river flows on a topographic map. contour lines point upstream rivers flow downhill

  18. What are the steps to draw a topographic profile place a piece of paper between the points mark where every contour line touches the edge of the paper determine the elevation of each mark place the paper on the graph and mark the elevation of each contour line

  19. Using the map and chart below, construct a topographic map profile.

  20. Please match the contour map on the left with the profile on the right.

  21. Topographic Maps---Distance Between Points What is the distance, in kilometers, from Kingston to Oswego? 266 km What is the distance, in miles, from Plattsburgh to Jamestown? 342 miles

  22. The elevation of Albany is 282 feet. The elevation at Binghamton is 1634 feet. Calculate the gradient to the nearest tenthof a ft/mi. Show all work. gradient = change in elevation distance = 1634-282 115 miles = 1352 ft 115 miles = 11.8 ft/mile

  23. The elevation of Watertown is 99m. The elevation at Oswego is 144m. Calculate the gradient to the nearest tenthof a m/km. Show all work. gradient = change in elevation distance = 144 - 99 75 km = 45 m 75 km = 0.6 m/km

  24. If the distance between the two circled cities is 425 km, calculate the temperature gradient to the nearesthundredth? Show all work. gradient = change in temperature distance = 82-48 425 = 34 425 = 0.08 °F/km
