Use FIGURE6 to create a base map of rainfall patterns, and then use FIGURE7 to add the population overlay. Use the checklist provided to make sure you complete all aspects of the task. 2. Once you have created your overlay map, answer the following questions using the skills you developed in this SkillBuilder. a. Look carefully at your base and overlay maps and hunt for patterns between them. Find examples where rainfall and population: i. mostly coincide with each other
ii. sometimes coincide with each other iii. do not coincide at all with each other.
b. Describe these areas, either by percentage or by the amount of overlap. c. How strong is the spatial association (relationship) between the following?
i. High rainfall and high population density ii. Low rainfall and a low population density Checklist I have: • drawn in pencil ýrst and then added colour
• included BOLTSS on the base map • used light colours on the overlay • included a key on the overlay
