Question

The sun is the ultimate source for energy on the Earth.


Please select the best answer from the choices provided

Answer 1

True. Nearly all of Earth's usable energy ultimately comes from the Sun: sunlight powers photosynthesis (biomass and, over geologic time, fossil fuels), drives the atmosphere and oceans (wind, waves, weather, and the hydrologic cycle used by hydroelectric power). Exceptions include geothermal energy (Earth's internal heat), tidal energy (Moon/planetary gravity), and nuclear fission (radioactive decay), which do not originate from the Sun.
