1. We will use POINT & EVIDENCE / EXPLANATION to answer our questions…..
1. 4 mark question = 2 points & evidence / explanation
2. 6 mark question = 3 points & evidence / explanation
3. 8 mark question = 4 points & evidence / explanation
Explain why the future growth rate of the worlds population is hard to predict? (6)
1. Point
Future growth rates are hard to predict because new diseases might occur in the future that we have not yet heard of.
1. Explanation / Evidence
These could cause death rates to increase because we don’t have the medicines to cure them, for example bird flu.
2. Point
Another reason is because resources like food and oil might run out.
