  1. Latitude and Longitude

  2. LATITUDE • Distance in degrees N and S of the Equator It is like the x-axis on a graph • Equator = 00 • Poles = 900 • Parallel lines, no matter what kind of map you have • Parallel lines never meet • 10 Lat = 111 km on Earth’s surface

  3. Latitude of a Point on the Map 1.FIND LATITUDE a. follow the horizontal line on which your point lies. Write that number. b. If the point is NORTH of the EQUATOR, write an N after the number; if it is SOUTH of the EQUATOR, write an S after the number. **Complete the “-DO ON YOUR OWN” section for Latitude.

  4. LONGITUDE • Distance in degrees E and W of the Prime Meridian It is like the y-axis on a graph • Prime Meridian = 00 • Int’l Date Line = 1800 • Curved lines on globes, large semi-circles from pole to pole; may be parallel on some maps • Lines all meet at the poles • Because lines are all curved, actual distances between lines on Earth’s surface vary

  5. Longitude of a Point on a Map 2.FIND LONGITUDE a. follow the vertical line on which your point lies. Write that number. b. If the point is EAST of PRIME MERIDIAN, write an E after the number; if it is WEST of the PRIME MERIDIAN, write a W after the number. **Complete the “-DO ON YOUR OWN” section for Longitude.

  6. NW NE SE SW

  7. Time Zones • Time zones correspond to lines of longitude • (Along the Equator) 15° longitude = 1 hour • (From the Prime Meridian) Moving WEST you subtract an hour for each line of longitude; moving EAST you add an hour for each line of longitude. • Earth has 24 lines of longitude, 24 hours in a day and 24 time zones. • When crossing the International Date Line from the east to the west you advance to the next day; from west to the east you go back one a day. • Complete the “-DO ON YOUR OWN” section for Time Zones.
