    • What is the Earth’s Grid?
    • Table of Contents
      • Latitude
      • Longitude
      • Conclusion

    • Latitude
      • Latitude lines are the angular distances measured north and south of the Equator . Latitude lines are also know as Parallels.
      • The lines become progressively shorter as ones moves toward the North or South Pole.
      • 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.
      • There are 60 minutes of latitude between every degree and 60 seconds of latitude between every minute.
      Next Table of Contents
    • Equator
      • The Equator is the longest Latitude line, it divides the Earth into a north half and a south half.
      • Therefore it is located halfway between the North Rotational Pole and The South Rotational Pole.
      • The Latitude of the Equator is 0 degrees because you measure distances North and South of it.
      • The Equator is 25, miles long.

    • Answer Question 1.)
      • On the map it looks like 40 degrees.
      • On proper map Indianapolis is
      • 39 degrees and 45 feet North Latitude

    • Answer Question 2.)
      • 40 Degrees North Latitude

    • Longitude
      • Longitude lines are the angular distances measured east and west of the Prime Meridian.
      • These lines only go half way around the Earth, forming half-circles.
      • Longitude lines are also known as meridians.
      • They being and end at a rational pole and are roughly the same length.
      Table of Contents Next
    • Prime Meridian and International Date Line
      • The Prime Meridian is the zero (0) degree longitude line because angular distances are measured east and west of it.
      • It begins at the North Pole and runs through the Royal Observatory in Greenwich, England and continues all the way to the South Pole.
      • The Prime Meridian goes half way around the earth.
      • The International Date Line is also the 180 degree longitude line.
      • Which is the highest numbered longitude line.
      • It is located opposite the Prime Meridian.
      • 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.
      • 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.

    • Conclusion
      • In conclusion the Earth’s Grid is the network of parallels and meridians super imposed on Earth’s surface used to locate features.
      • 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.
