Which energy source uses heat from underground rocks or water to produce energy?

• A. Wind Energy
• B. Solar Power
• C. Uranium
• D. Geothermal Energy

Answer: (D)

Geothermal energy uses heat from underground rocks or water. The Earth’s interior keeps some rock and groundwater very hot. By drilling into those reservoirs, we bring hot fluid or steam to the surface, where it can spin turbines to make electricity or provide direct heat for buildings. This is different from wind energy, which relies on moving air; solar power, which uses sunlight; and uranium, which releases energy through nuclear fission. So, geothermal energy is the energy source described.
