  • 1. What is the Earth’s Grid?
  • 2. Table of Contents <ul><li>Latitude </li></ul><ul><li>Longitude </li></ul><ul><li>Conclusion </li></ul><ul><li>Works Cited </li></ul>
  • 3. Latitude <ul><li>Latitude lines are the angular distances measured north and south of the Equator . Latitude lines are also know as Parallels. </li></ul><ul><li>The lines become progressively shorter as ones moves toward the North or South Pole. </li></ul><ul><li>The 60 degree latitude lines is very useful for quickly assessing are distortions on maps. It is also on-half the length of the equator. </li></ul><ul><li>There are 60 minutes of latitude between every degree and 60 seconds of latitude between every minute. </li></ul>Next Table of Contents
  • 4. Equator <ul><li>The Equator is the longest Latitude line, it divides the Earth into a north half and a south half. </li></ul><ul><li>Therefore it is located halfway between the North Rotational Pole and The South Rotational Pole. </li></ul><ul><li>The Latitude of the Equator is 0 degrees because you measure distances North and South of it. </li></ul><ul><li>The Equator is 25, miles long. </li></ul>Next Table of Contents
  • 5. Review <ul><li>1.) Where is Indianapolis located ? </li></ul><ul><li>Map Answer </li></ul><ul><li>2.) If Indianapolis is situated 15 minutes of its present location, what would its latitude then be? </li></ul><ul><li>Answer </li></ul>Table of Contents
  • 6. Map Table of Contents Back to Review Answer
  • 7. Answer Question 1.) <ul><li>On the map it looks like 40 degrees. </li></ul><ul><li>On proper map Indianapolis is </li></ul><ul><li>39 degrees and 45 feet North Latitude </li></ul>Table of Contents Back to Review
  • 8. Answer Question 2.) <ul><li>40 Degrees North Latitude </li></ul>Table of Contents Back to Review
  • 9. Longitude <ul><li>Longitude lines are the angular distances measured east and west of the Prime Meridian. </li></ul><ul><li>These lines only go half way around the Earth, forming half-circles. </li></ul><ul><li>Longitude lines are also known as meridians. </li></ul><ul><li>They being and end at a rational pole and are roughly the same length. </li></ul>Table of Contents Next
  • 10. Prime Meridian and International Date Line <ul><li>The Prime Meridian is the zero (0) degree longitude line because angular distances are measured east and west of it. </li></ul><ul><li>It begins at the North Pole and runs through the Royal Observatory in Greenwich, England and continues all the way to the South Pole. </li></ul><ul><li>The Prime Meridian goes half way around the earth. </li></ul><ul><li>The International Date Line is also the 180 degree longitude line. </li></ul><ul><li>Which is the highest numbered longitude line. </li></ul><ul><li>It is located opposite the Prime Meridian. </li></ul><ul><li>It is called the International Date Line because when you travel west of it you add a day and when you travel east of it you subtract a day. </li></ul><ul><li>But the International Date Line is not directly on the 180 degree longitude line; it zigzags through the Pacific Ocean to avoid splitting countries and island group. </li></ul>Picture of Prime Meridian Picture of International Date Line Table of Contents Next

  • 13. Review <ul><li>1.) Where is Indianapolis located? </li></ul><ul><li>Map Answer </li></ul><ul><li>2.) What country does the intersection of 15 degrees South Latitude and 65 degrees West Longitude occur? </li></ul><ul><li>Map Answer </li></ul>Table of Contents
  • 14. Answer Question 1.) <ul><li>86 degrees and 8 feet West Longitude </li></ul><ul><li>Back to Review </li></ul><ul><li>Table of Contents </li></ul>

  • 16. Back to Question Answer
  • 17. Back to Question Answer
  • 18. Conclusion <ul><li>In conclusion the Earth’s Grid is the network of parallels and meridians super imposed on Earth’s surface used to locate features. </li></ul><ul><li>I have never done a presentation like this and it was very eye opening. The presentation can go where ever you want it to. I don’t have to click and click to get back to a particular slide. I like that I can click backwards as well. I also liked all the animation features, it really spices up the presentation. </li></ul>Works Cited Table of Contents
