  1. The Global Grid

  2. The global grid makes it possible to state the “absolute location” of a place – exactly where it is. http://www.psdgraphics.com/backgrounds/world-globe-background/ http://matagalatlante.org/nobre/featpost/doc/featexamples.html

  3. Absolute location – longitude & latitude – is like a global address. http://amyrondinel.com/2010/09/home-is-where-the-heart-is/

  4. Los Angeles, California: 34°N 118W° http://www.hightunnels.org/ForEducators/Planning/FullMoonFarmCaseStudy/planningorientationlatitude.htm

  5. Washington, DC: 38°N 77W°

  6. Seattle, Washington: 47°N 122W°

  7. Tulsa, Oklahoma: 36°N 95°W

  8. Oklahoma City: 35°N 97W°

  9. The absolute location of any place is the latitude + the longitude. http://www.ukdivers.net/chartwork/chartintro.htm

  10. LATITUDE http://www.ukdivers.net/chartwork/chartintro.htm

  11. LATITUDE lines are the FLAT lines. http://www.ukdivers.net/chartwork/chartintro.htm

  12. LATITUDE lines also get shorter as you get closer to the North Pole or the South Pole. http://www.ukdivers.net/chartwork/chartintro.htm

  13. Latitude lines run flat east and west, but they tell how farnorthor south you are of the Equator.

  14. Think of latitude like the rungs of a ladder. (Ladder sounds a lot like latitude). It’s how you go up and down the globe. http://geographyworldonline.com/tutorial/lesson1.html

  15. Anywhere you are on the 30°N line, you are 30°northof the Equator.

  16. And anywhere you are on the 30°S line, you are 30°southof the Equator.

  29. Two other “famous” lines of latitude are the Tropic of Cancer and the Tropic of Capricorn. http://usdoctor.tistory.com/115

  30. So remember to think of latitude like the rungs of a ladder. http://www.nauticus.org/currptpless01.html http://www.shoponline2011.com/m~c-laptop-computers~b-462~f-1-646838_679798-679809.aspx

  31. Latitude is how you go up and down the globe.

  32. up or down the globe (northor south). So latitude is all about how far you are from the Equator –

  33. questions on latitude. . .

  34. LONGITUDE http://www.ukdivers.net/chartwork/chartintro.htm

  35. Longitude lines are always long.

  36. Lines of longitude get closer togetheras they move away from the Equator & to the poles. http://www.mapsfordesign.com/North-Atlantic-Ocean-Global-Projection-PowerPoint-Map.html

  37. And longitude lines actually all meet at the poles. http://www.mapsfordesign.com/North-Pole-Global-Projection-PowerPoint-map.html http://www.mapsfordesign.com/South-Pole-Global-Projection-PowerPoint-Map.html

  38. Longitude lines tell us how far east or west we are from the Prime Meridian. http://www.ukdivers.net/chartwork/chartintro.htm

  39. Anywhere you are on the 30°E line, you are 30°eastof the Prime Meridian. http://www.hammondmap.com/catalog/classroom_activities/latlong1.html

  40. Anywhere you are on the 30°W line, you are 30°westof the Prime Meridian. http://www.hammondmap.com/catalog/classroom_activities/latlong1.html

  41. The Equator is a real location. But who decided where to put the Prime Meridian?

  42. In the 1500s, when the Portuguese controlled the Atlantic, they drew the first Prime Meridian passing through the Madeira Islands. Graphicmaps.com

  43. http://www.fotosearch.com/clip-art/spanish.html Portugal owned the Madeira Islands, so they thought it was a good idea to use THEIR land for the Prime Meridian location. We control the Atlantic. So, of course, it makes perfect sense that we would put the Prime Meridian through OUR land. WE are the center of the world! Graphicmaps.com

  44. http://www.math.nus.edu.sg/aslaksen/gem-projects/hm/0203-1-10-instruments/glossary.htmhttp://www.math.nus.edu.sg/aslaksen/gem-projects/hm/0203-1-10-instruments/glossary.htm This Prime Meridian was used by most mapmakers for the next 300 years.

  45. When the British got control of the Atlantic, they set a new Prime Meridian, right through England! Graphicmaps.com

  46. NOW look who’s in charge of the Atlantic! England is now the center of the universe, so we will re-draw the Prime Meridian to go through England! http://colquitt.k12.ga.us/wjwpg2/Explorers/explor.htm Graphicmaps.com

  47. In 1884, 25 countries reached agreement at a conference in Washington D.C. that the location in Greenwich, England, would be the “Prime Meridian” - zero degrees.Over a period of many years, other countries accepted and adopted the decision. http://www.brannelastronomy.com/articles/meridian.htm
