WHERE AM I?

1. WHERE AM I? O 30 N LATITUDE 90 W LONGITUDE O

2. Location and distance are stated using a system known as latitude and longitude. The Relative Location is the location of a place in relation to another place The absolute location for a place is the exact spot on the earth’s surface where a place is found. The line of latitude is always read first followed by the line of longitude. Location

3. A B C D E F G 1 2 3 4 5 6 8

4. Where are the Parish Seats? Baton Rouge, LA F-6 Patterson, LA H-6 Thibodaux, LA H-7

5. A-5 Bastrop B-3 Arcadia G-7 Convent

6. Latitude • Imaginary lines running east and westaround the globe • Measured in degrees north and south of the equator. • Latitude lines are called parallels because each line is parallel to the next

7. Latitude • Degrees are units of measurement for latitude and longitude. • The symbol for degrees is °. • The equator is the imaginary line that circles the Earth’s center known as 0° latitude.

8. North of the equator EQUATOR South of the equator • Parallels above the equator are in the Northern Hemisphere, all below are in the Southern Hemisphere

9. Hemispheres • The equator divides the Earth into two equal parts called Hemispheres • There is a Northern Hemisphere and a Southern Hemisphere • Both hemispheres begin at the equator or zero degrees latitude

10. HEMISPHERES

11. Hemispheres • The Northern Hemisphere begins at 0° latitude and ends at 90° North latitude • 90° North latitude is located at the North Pole. • The Southern Hemisphere begins at 0° latitudeand ends at 90° South latitude • 90° Southlatitude is located at the South Pole.

12. You must write latitude coordinates like this: Northern Hemisphere Latitudes ˚ _____ N LAT Southern Hemisphere Latitudes _____ S LAT ˚

13. Longitude • Distance measured in degrees east and west of the prime meridian. • Longitude lines are called meridians.

14. Longitude • The prime meridian is the starting point for measuring longitude. • The prime meridian is 0 longitude which goes through the space observatory in Greenwich, England. ˚

15. Meridians west of the prime meridian are in the western hemisphere, all in the east of the prime meridian are in the eastern hemisphere. Prime Meridian Western Eastern Hemisphere Hemisphere

16. Hemispheres • The Eastern Hemisphere begins at 0° longitudetraveling east and ends at 180° longitude • 180° longitude is located exactly half way around the world from 0°longitude. • The Western Hemisphere begins at 0° longitudetraveling west and ends at 180° longitude • 180° longitude is located exactly half way around the world from 0°longitude.

17. HEMISPHERES

18. You must write longitude coordinates like this: Western Hemisphere Latitudes ˚ _____ W Long Eastern Hemisphere Latitudes _____ E Long ˚

19. WHERE AM I? O 30 N LATITUDE 90 W LONGITUDE O

20. TIME ZONES

22. Time Zones(Read more on page 25) • Earth has 24 time zones. • United States has six. • Pacific, Mountain, Central and Eastern are the four time zones in the continental United States. • Think about how the television stations report when your favorite shows come on (ex-7 central) GLEs: 1

23. U.S. Time Zones

24. TIME ZONES • The earth rotates on its axis once every 24 hours. For this reason, the earth is divided into 24 standard time zones, one time zone for each hour in the day. • The earth rotates towards the east • which means that if you cross into the next time zone to the east, it is one hour later. If you cross into the next time zone in the west, it is one hour earlier.

25. Where does time start? The International Date Line plays an important role in time zones. It is located at 180 degrees longitude. If you are standing on the east side of the International Date Line it is one day (Monday); however, on the west side, it is a day ahead (Tuesday).
