4. a. Outline the difference between blue and green water. b. List two things that might change the amount of blue and green water available. 5. Study FIGURE5 and an atlas. a. Select three regions from the following list that are predicted to receive more run-off due to climate change. A. Northern, southern and north-east Africa B. Europe — Scandinavian countries and the United Kingdom C. South America — south-east Brazil, Uruguay and northern Argentina D. Australasia — northern Australia and the South Island in New Zealand E. South America — eastern Argentina and Chile, Brazil and the northern countries, and all of Central America b. Select three regions from the following list that are predicted to receive less run-off due to climate change. A. Northern, southern and north-east Africa B. Europe — Scandinavian countries and the United Kingdom C. South America — south-eastern Brazil, Uruguay and northern Argentina D. Australasia — northern Australia and the South Island in New Zealand E. South America — eastern Argentina and Chile, Brazil and the northern countries, and all of Central America ANALYSE AND APPLY 6. Study FIGURE3 . Identify which of the following statements are true. Rewrite any false statements to make themtrue. a. Most places with very low rainfall have lower run-off. b. All places with very high rainfall experience increased run-off. c. The places with the greatest change in run-off will be northern Russia and northern Canada. EVALUATE AND COMMUNICATE 7. Study FIGURES3 and 5 . a. Describe how much rain falls in North Africa and West Asia (the Middle East). b. Identify what is predicted to happen to annual run-off in the regions of North Africa and West Asia as a result of climate change. What impact might this have on people and the environment? 8. Refer to FIGURES7 and 9 . a. Determine the climate zone in Australia that has the most rainfall variability and the climate zone that has the least rainfall variability. b. Predict the factors that may contribute to this variation in rainfall reliability across Australia. 9. Explain the interconnection between climate change and extreme weather events in Australia Answers and sample responses for this topic are available online.
