  2. 2. Earth’s Reference Points <ul><li>First step in mapping earth’s surface is to set up reference points. </li></ul><ul><li>Equator – imaginary line that divides the northern hemisphere from the southern hemisphere. </li></ul><ul><ul><li>Labeled 0° </li></ul></ul>
  3. 4. Latitude & Longitude <ul><li>When you place a point on a graph you need to know how far left or right (x-axis) and how far up or down (y-axis.) </li></ul><ul><li>Latitude – parallel lines that run left and right and dictate how far NORTH and SOUTH of the Equator. </li></ul><ul><ul><li>Range from 0° to 90° </li></ul></ul>
  4. 6. Latitude & Longitude CONT’D <ul><li>Longitude – lines that run from up and down and dictate how far EAST and WEST from the Prime Meridian. </li></ul><ul><ul><li>Range from 0° to 180° </li></ul></ul>
  5. 8. Prime Meridian <ul><li>Prime Meridian – main line of longitude passing through Greenwich, England. </li></ul><ul><ul><li>Labeled 0° </li></ul></ul>
  6. 9. Map Projections <ul><li>A globe represents the spherical earth very accurately because both the globe and earth are round. </li></ul><ul><li>Flat map projections don’t represent the earth as accurate as a globe. </li></ul><ul><li>Why? </li></ul>
