r yNamev., .lIP .,4ji. i.- What Is Latitude? How Is It Measured?1. Lines of latitude are imaginary lines that ." run completely around the globe-full circles. If you travel along any of these l lines youare going east or west.2. The equator is numbered 0 degrees or 0 .The equator divides the world into twohalves or hemispheres: the Northern Hemisphere and the Southern Hemisphere. Allplaces that are north of the equator are saidto have north latitude. All places south of theequator are said to have south latitude. So,c:.! place Aon the diagram below is on the 10 latitude line. A simple way to write 10 rs northis looN. northPlace C is on the 10 south latitude line,"E1\1 or 100S. What is the latitude of Place B?41 ,I 't \.;.;;-from 0 , the equator, the lines of latitude arenumbered north and south to 90 . The NorthPole is 900N, and the South Pole is 90 0S.5. Here i an opportunity to practice findingthe latitudes of a number of places. Place Ahas been given its latitude to help you getstarted.N'I P 10110170- , /101/lOlL40-/30- L20- I .100110-20' .\30-.\401 cc: .S!"a.Q,Your answer should be200N.

All lines of latitude are parallel. Thismeans that no matter how far two lines of latitude are extended they would never meet. So,on the diagram above you can see that theequator, the lOON line of latitude and the 100Sline of latitude are parallel. In fact, sometimes lines of latitude are called parallels.4. To prevent maps from becoming too cluttered with lines, map makers show only a fewlines of latitude, generally 10 or 20 degreesapart.The diagram in the next column showslines of latitude that are 10 apart. StartingL:S. You can easily determine how many degrees separate one place from another place.For example, B is on the SOON line of latitude; C is on the 400N line of latitude. Bysubtracting we find that B is 20 furthernorth than C.How many degrees of latitude separate:F:C from D? 'E from F?G from K?C from I? - - -

(INSTRUCTOR)1-3 UNDERSTANDING LONGITUDEYour students have learned that latitudemeasures distances north and south of theequator. Now it is important that they learnhow to locate places on iinesof latitude. Suppose someone at sea reported that they werelocated on the 200N line of latitude. A firstquestion would be, "Where on the 200N lineare you located?" After all, the 200N linegoes all the way around the world-·morethan 23,000 miles!( 3. All same-numbered east or west linesof longitude are equidistant apart at theequator. . ,.4. All lines of longitude are measured· eastor west of the prime meridian. Prime meridian is another way of saying the 0 line oflongitude.5. Lines of longitude are often shown onmaps as being 10 apart at the equator.Sometimes they are shown as being 15 apart, or even 30 apart. How they arespaced and numbered depends on the purpose of the map.To locate places exactly on a globe ormap it is necessary to have north-southlines-lines of longitude-that cross theeast-west lines of latitude. Once it is knownwhere the lines cross, any place on the globecan be given an exact location.6. The numbering of the lines continues for1800 to the east, and 180 to the west, for atotal of 3600 , a full circle.Here are some important facts aboutlines of longitude: -- . .,.c.sa::s'"." .5.c ca7. The prime meridian and its continuationon the other side of the world, 1800 , dividesthe world into two equal parts: The EasternHemisphere and the Western Hemisphere.1.

Later, you will apply yourknowledge of both latitude and longitude tolocate places around the world.1. The lines of latitude on the diagram beloware 15 apart. Notice that some of the linesare not numbered, that there are blank boxeson those lines. Study the numbers on theother lines, then print the ·proper numbers inthe boxes.2.
