3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
Different strategies can be used to increase water supply. Strategies to increase water supply include diverting supplies, increasing storage and desalination.
2. Define this geography term and use it in an example. 'water transfer'
the movement of water (through pipes or along rivers) from areas of water surplus to areas of water deficit.
3. Correct this common geography misunderstanding.
Mistake: Dams and reservoirs guarantee a reliable water supply for many years into the future. Correction: Although dams and reservoirs do provide a reliable and easily-controllable source of water, this supply is not guaranteed. Over time, sediment will build up and reduce the capacity of the reservoir. Also, reservoirs can dry up during droughts.
