Most of the sources of energy that we use represent stored solar energy. Which of the following is not ultimately derived from the sun's energy?
(a) wind energy
(b) geothermal energy
(c) fossil fuels
(d) biomass
Correct Answer: (b) geothermal energy
Explanation:
Wind energy, fossil fuels and biomass are derived from the sun's energy. They represent the stored solar energy.
While geothermal energy represents the stored energy of the core of the Earth.
