30
Where in the UK is there a water **surplus**?
The north and west
31
Where in the UK is there a water **deficit**?
The south and east
32
What is '**water** **stress**'?
When **demand** for water is **greater** than the **supply** of water
33
Name **3** ways that water savings can be made?
1. Household water meters 2. Using recycled water 3. More efficient use of household appliances e.g. washing machines

46
What is '**fracking**'?
The process of extracting shale gas from under the ground
47
Explain how **fracking** works
High pressure liquids are pumped underground to release gas trapped within sedimentary rock.
48
Why is **fracking** controversial?
* Drilling can trigger earthquakes * Can pollute underground water sources * Expensive process
49
What are the **economic** impacts (+ and -) of **nuclear** **power**?
