Geothermal energy is harnessed by:
ADrilling pipes into hot underground regions where steam is generated
BBurning fossil fuels by common convention
CCapturing sunlight underground across all cases
DStoring rainfall in general usage in the standard view
Answer & Solution
Correct answer: A. Drilling pipes into hot underground regions where steam is generated
1. Some regions have hot rocks close to the surface (hot spots).
2. Drilled pipes circulate water down to these hot rocks.
3. Water flashes to steam at the hot zone.
4. The steam rises and drives a turbine to generate electricity.
5. So geothermal energy is captured by drilling into hot underground regions.
