Question 1: In areas of enhanced heat flow,
geothermal heating can be used to supply heating to homes, either
by using ground water directly or by placing a water reservoir at
depth. In Iceland, where the average temperature over the year is
4.6ºC, the geothermal flux can be as high as 300 mW
m-2.
- If you wanted to be able to supply a home with indoor
temperature at 25ºC and water at a temperature of 55ºC, how deep
would your reservoir need to be? (1 mark)
- Why might Iceland have such a high geothermal flux compared to
other areas?
- Does high geothermal flux accelerate the melting of ice sheets,
why or why not?
