Earth receives large amount of energy directly from:
Correct answer: C. Sun
- 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.

About Energy Losses and Efficiency
Efficiency compares useful output energy or power with the total input, usually expressed as a percentage. The topic covers energy losses through friction, heating, resistance and sound, along with power ratings and Sankey diagrams. Efficiency is not the same as conservation of energy, because lost energy is transferred rather than destroyed.
