Question 1: In areas of enhanced heat flow,geothermal heating can be used to supply heating to homes, eitherby using ground water directly or by placing a water reservoir atdepth. In Iceland, where the average temperature over the year is4.6ºC, the geothermal flux can be as high as 300 mWm-2.
- If you wanted to be able to supply a home with indoortemperature at 25ºC and water at a temperature of 55ºC, how deepwould your reservoir need to be? (1 mark)
- Why might Iceland have such a high geothermal flux compared toother areas?
- Does high geothermal flux accelerate the melting of ice sheets,why or why not?
