Geography Skills: Scale

  1. 1. GEOGRAPHYSKILLS:SCALE Created by tbonnar.
  2. 2. Map Scale A scale is a statement of the relationship between distances on a map and distances in real life. A drawing that is made according to scale will be an exact copy of the real object, but will be smaller or larger than the real object.
  3. 3. Map Scale Scale drawings are often used in real life because they are very accurate, including in maps, blueprints, and architectural models.
  4. 4. Section A:Three Types of Scale
  5. 5. Three Types of Scale There are three different ways to write scale. Stated • 1 cm = 250 km Scale Linear Scale Ratio • 1:25 000 000 Scale
  6. 6. Map ScalesStated Scale 1 cm = 8 km A stated scale says exactly how much distance is represented by 1 cm, in this case, 8 km. It is the most useful scale for calculating distances. 1 cm = 8 km
  7. 7. Map ScalesLinear Scale: A linear scale is usually present on most maps. It tells us how much map distance represents a certain real distance. For example, the scale shows the map distance that equals 10 kilometers in real distance.
  8. 8. Map ScalesRatio Scale A ratio scale will almost always be found on maps. It is very accurate. In this example we can see that 1 unit on the map represents 25 000 000 units in real life. So, 1 cm = 25 000 000 cm and 1 m = 25 000 000 m, etc.
  9. 9. Map Scales: ChangingScales Distances such as 25 000 000 cm are very difficult to imagine. So, we usually change a ratio scale into a stated scale. In this example, we would use the metric system to help us change the ratio scale of 1:25 000 000 into a stated scale of 1 cm = 250 km.
  10. 10. Section B:Metric System Review
  11. 11. Metric System Review Recall that the metric system is based on multiplying and dividing by 10. To change from one unit to another you just need to multiply or divide by 10 the correct number of times.
  12. 12. Metric System Review
  13. 13. Metric System Review Another way to say this is that you just need to move the decimal place the correct number of spaces to the left (dividing) or right (multiplying). For scale calculations, you need to learn a quick method of changing units.
  14. 14. Metric System ReviewQuick Method of Changing Unitsa) To change cm into km, move your decimal five places to the left. ex. 550 000 cm = 5.5 kmb) To change km into cm, move your decimal five places to the right. ex. 72 km = 7 200 000 cm
  15. 15. Metric System ReviewPractice 1. Make the following conversions using the shortcut method.a) 47 000 cm = km d) 89 km = cmb) 321 400 cm = km e) 6.5 km = cmc) 4 000 000 cm = km f) .54 km = cm
  16. 16. Metric System ReviewPractice 1. Make the following conversions using the shortcut method.a) 47 000 cm = 0.47 km d) 89 km = 8 900 000 cmb) 321 400 cm = 3.214 km e) 6.5 km = 650 000 cmc) 4 000 000 cm = 40 km f) .54 km = 54 000 cm
  17. 17. Section C:Changing fromRatio Scale to Stated Scale
  18. 18. Changing from Ratio Scale to StatedScale It is easiest to calculate distance using a Stated Scale, but most maps don’t include Stated Scales. So, to change Ratio Scale into Stated Scale, do the following. Stated Scale• 1:25 000 000 • 1 cm = 250 km Ratio Scale
  19. 19. Changing Scales1. Write the Ratio Scale.  1:550 0002. Change it to a Stated Scale.  1 cm = 550 000 cm3. Change the Stated Scale Units from cm into km, by moving your decimal five places to the left.  1 cm = 5.5 km
  20. 20. Changing ScalesPractice 2. Find the ratio scale of the main map and change it to a stated scale.ex. p1321 : 44 000 0001 cm = 44 000 000 cm1 cm = 440 kma) p65 b) p116 c) p136 d) p71
  21. 21. Changing ScalesPractice 2.a) p65 b) p1161: 7 000 000 1 : 13 000 0001cm = 7 000 000cm 1cm = 13 000 000cm1cm = 70km 1cm = 130kmc) p136 d) p711:25 000 000 1:50 0001cm=25 000 000cm 1cm = 50 000cm1cm = 250km 1cm=0.5km
  22. 22. Section D: Solving scale questionsusing cross-multiplication Now that you know how to change a ratio scale into a stated scale, you can calculate the real distance between two places shown on a map. To do so though, you need to know how to cross-multiply.
  23. 23. Solving scale questionsusing cross-multiplication Practice 3. Solve these questions using cross-multiplication. a) 1 4 b) 1 12 5 x 40 x c) 1 25 d) 1 300 350 x 4500 x
  24. 24. Solving scale questionsusing cross-multiplication Practice 3. Solve these questions using cross-multiplication. a) 1 4 b) 1 12 5 x 40 x c) 1 25 d) 1 300 350 x 4500 x
  25. 25. Section E: Five Stepsto Calculate Real DistanceNow, you are ready to calculate the real distances betweenplaces shown on a map by following these five simple steps. Step A. Find the ratio scale. Step B. Change the ratio scale into a stated scale. Step C. Measure the map distance in cm. Step D. Use cross-multiplication to solve this equation: scale (cm) = map distance (cm) scale (km) real distance (km) Step E. Write a conclusion (a therefore statement). Include the country names.
  26. 26. Section E: Five Steps to Calculate Real Distance Example: Madrid to MoscowStep A 1:25 000 000Step B 1 cm = 250 kmStep C m.d. = 13.2 cmStep D scale (cm) = map distance (cm) scale (km) real distance (km) 1 cm = 13.2 cm 250 km x 1x = 13.2(250) x = 3300 kmStep E Madrid, Spain is 3300km from Moscow, Russia.
  27. 27. Section E: Five Steps to Calculate Real Distance Example: Casablanca to CairoStep A 1:37 000 000Step B 1 cm = 370 kmStep C m.d. = 10.2 cmStep D scale (cm) = map distance (cm) scale (km) real distance (km) 1 cm = 10.2 cm 370 km x x = 3374 kmStep E Casablanca, Morocco is 3774 km from Cairo, Egypt.
  28. 28. Map Scales:Large Scale vs. Small Scale
  29. 29. LargeScale vs.SmallScal
  30. 30. Map Scales: Large Scale vs. Small Scale A map showing the whole world is on a very small scale (1:360 000 000 000) which allows for an overall view, but not much detail. Small scale maps are ideal for travelling by car because they cover large areas of land. 1:250 000
  31. 31. Map Scales:Large Scale vs. Small Scale A town plan is on a much larger scale so that features such as roads can be shown clearly (1cm:500m) Large scale maps are better for showing individual buildings in detail because they only cover a small area of land.
