The majority of the energy processes at the earth’s surface comes from the earth’s internal energy
aliya0001 [1]

Answer:

True, majority of the earth energy source comes from the <u>internal motion</u> but rest comes from outside.

Explanation:

  • Earth gets its energy from the interior of the planet like the core which forms the most essential driving force of the planet it not just only regulate the flow of geomaterial from the bottom to the top but also acts as a geothermal source for various energy process.
  • As we know this is called the Endogenetic force of the planet caused due to the earth rotation without which earth would have been dead long ago. The external forces of Denudation which break down the landscape from above are of Exogenic in nature.  
  • The sun's rays that are 100% at the surface of the earth but, come down o only 50% at the ground level as most of it gets deflected by the natural Albedo of the earth with is 35%. This partial absorption, deflection, and then reflection  
  • Thus this process is a temporary phase as all this gets reradiated back in a long wave from at night.
  • Thus internal thermodynamics has a huge role to play in the formation of earth energy processes.
