  2. Latitude and Longitude • Are these lines latitude or longitude? • What directions do they measure? Latitude! North and South

  3. Latitude and Longitude • Are these lines latitude or longitude? • What directions do they measure? Longitude! East and West

  4. Line of Longitude • Where are the lines of longitude closest together? • Where are they furthest apart? • Where would traveling 7.5° take you the farthest distance across land? North and South Poles Equator Near the Equator!

  5. What is the altitude of Polaris? 42°N What does the altitude of Polaris equal? Your Latitude!

  6. Finding the Altitude of Polaris • If you were on the North Pole, what would be your latitude? Note: Polaris is known as our celestial reference point because it is located over Earth’s axis of rotation.

  7. Finding the altitude of the North Star Where do you see the north star level with the horizon? The Equator

  9. Can you use Polaris to determine your latitude in the Southern Hemisphere? • Why or Why not? No! The North Star is not visible in the southern hemisphere

  10. Earth’s Layers • Describe the layers of the earth in terms of density. Least dense Most dense
