maps

  1. 1. WORKING WITH MAPS Geography topic 9
  2. 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. 3. PARALLELS EQUATOR: THE PRINCIPAL PARALLEL. PARALLELS ARE NUMBERED FROM THE EQUATOR TO THE POLES IN DEGREES 0º TO 90º NORTH or SOUTH.
  4. 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. 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. 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. 7. CO-ORDINATES WHEN WE PUT THE LATITUDE AND LONGITUDE OF A PLACE TOGETHER WE HAVE THE CO-ORDINATES OF THE LOCATION.

  9. 9. EXERCISES
  10. 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. 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.
