  1. PRIME MERIDIAM OF THE WORLD
  2. What is the Meridian Line? <ul><li>The Meridian Line is an imaginary line which runs from the North Pole to the South Pole . </li></ul>
  3. <ul><li>For many years, different countries measured longitude from different meridians. The French and Algerians, for example, used the Paris Meridian; the Spanish measured from one that passed through Isla del Hierro . By the 1880s, many people could see the advantages of measuring from a single meridian. </li></ul>
  4. <ul><li>The imaginary line that separates East and West is the Prime Meridian. The Prime Meridian passes through Greenwich, England. </li></ul>
  5. <ul><li>By international convention it runs through &quot;the primary transit&quot; instrument (main telescope) at the Royal Observatory in Greenwich. </li></ul>
  6. Why does the Prime Meridian (Zero Longitude) pass through Greenwich? <ul><li>The International Meridian Conference took place in October 1884 in Washington DC. Twenty-five nations were represented at the conference by 41 delegates. The Greenwich Meridian was chosen to become the Prime Meridian of the World. There were several reasons for this; the main one being that nearly two thirds of the World's ships were already using charts based on it. </li></ul>
  7. How long is the Prime Meridian? <ul><li>From Pole to Pole, the Prime Meridian covers a distance of 20,000 km. </li></ul>
  8. Which countries does the Prime Meridian pass through? <ul><li>In the Northern Hemisphere, the Prime Meridian passes through the UK, France and Spain in Europe and Algeria, Mali, Burkina, Faso, Tongo and Ghana in Africa. </li></ul><ul><li>The only landmass crossed by the Meridian in the Southern Hemisphere is Antarctica. </li></ul>
