Earth receives large amount of energy directly from:

  • A. Wind
  • B. Water
  • C. Sun
  • D. Moon

Explanation

Solar radiation is the primary energy input to the Earth, and wind and flowing water are themselves driven by the uneven solar heating of the atmosphere and oceans, which makes them secondary rather than direct sources. The Sun's energy comes from the fusion of hydrogen into helium in its core. Tidal energy is the one significant contribution that traces back to the Moon instead.
