Transcript

  • 1. WORKING WITH MAPS Geography topic 9
  • 2. SCALES Here, 1 cm on the map represents 7,000 actual cm. This means: 1 cm on the map equals 70 meters in the real life Here, 1 cm on the map represents 500,000 actual cm. This means: 1 cm on the map equals 5000 meters in the real life. THIS MEANS: 5 km.
  • 3. PARALLELS EQUATOR: THE PRINCIPAL PARALLEL. PARALLELS ARE NUMBERED FROM THE EQUATOR TO THE POLES IN DEGREES 0º TO 90º NORTH or SOUTH.
  • 4. PARALLELS PARALLELS measure LATITUDE LATITUDE: is the distance between any point on the Earth to the equator. We talk about northern or southern hemisphere.
  • 5. MERIDIANS MERIDIANS: Imaginary lines that go from pole to pole. (like an orange). GREENWICH meridian ins the principal meridian so we call it PRIME MERIDIAN.
  • 6. MERIDIANS MERIDIANS: are numbered in degrees from 0 to 180º EAST or WEST. Meridians measure LONGITUDE which is the distance between any point on the Earth and the Greenwich meridian.We talk about eastern or western hemisphere
  • 7. CO-ORDINATES WHEN WE PUT THE LATITUDE AND LONGITUDE OF A PLACE TOGETHER WE HAVE THE CO-ORDINATES OF THE LOCATION.
  • 8. WEBSITES ! http://en.wikipedia.org/wiki/Spain http://en.wikipedia.org/wiki/Dublin http://es.wikipedia.org/wiki/Ushuaia http://en.wikipedia.org/wiki/Cape_Town http://es.wikipedia.org/wiki/Anexo:Puntos_extremos_del_mundo
  • 9. EXERCISES
  • 10. 1. Explain the advantages and disadvantages of representing the Earth using a globe and on a world map. 2. Calculate how many actual km equal 1 cm in the following scales. What type of scale are they? 1: 200,000 1: 50,000 1: 1,000,000
  • 11. GRAPHICAL SCALES 3.You are going to see three slides with three different maps. Write down the similarities and differences you can observe. 4. When it comes to use a graphical scale, in case you want to represent something with greater detail, would you:(explain your answer) a. choose a map in which 1 centimeter in the map represents 1 km in the real life.(1 actual km) b. choose a map in which 1 centimeter in the map represents 100 actual km.
  • 12. WHAT CONTINENT DO THESE COUNTRIES BELONG TO? RUSSIA JAPAN INDIA AUSTRALIA EGYPT BRAZIL URUGUAY NEW ZEALAND BOLIVIA MEXICO
