As such the fuel for earth’s Carbon cycle. Wouldn’t photons be the alleged “electromagnetic” mode of energy transfer into earth? Providing energy for the endothermic photosynthetic processes and heat for all and mass exposed to this energy modality. Mass can be gas, liquid or solid. In All instances converting thermic or light energy into increased molecular motion. What would be the vector for energy to be transferred out of earth atmosphere into the empty firmament.

  • $\begingroup$ Maybe the question was posed to assist in research, so we are to provide the details? $\endgroup$ Commented Dec 27, 2019 at 16:27
  • $\begingroup$ Extremely unclear question. Vector for energy input? Energy is a scalar. The carbon cycle is driven by planetary-scale plate tectonics and surface rain runoff, not photons. $\endgroup$ Commented Dec 27, 2019 at 19:41
  • $\begingroup$ The term vetcor (something with magnitude and direction) is somewhat mislplaced here. They are best used in analysis. The best way to radiate energy off into space is by infrared wavelengths leaving earth (open sky, no greenhouse gases) or by reflecting incoming radiation directly, e.g. cloud layers, ice covers, anything that has a high (attention, here it comes) albedo. Is that what you're asking ? $\endgroup$

    $\begingroup$ @Jorge you need to focus on one single question,as it is now after your edit it is way too broad.please take a look here earthscience.stackexchange.com/tour to see how to ask a question here on our site. $\endgroup$ Commented Dec 28, 2019 at 6:07

Photons do not emit energy but rather, carry stored kinetic energy that has the potential to give or TAKE AWAY heat so, to answer your question, they ARE an energy vector but would think they are not the fuel for the Carbon Cycle since they get scattered by particles and water vapour....which leads me to think they are part of the cocktail, but not the fuel in itself. Here is an excellent visual and summarized source for interactions of radiation with the atmosphere > https://www.nrcan.gc.ca/maps-tools-publications/satellite-imagery-air-photos/remote-sensing-tutorials/introduction/interactions-atmosphere/14635

I believe you have asked an excellent question and look forward to reading the subsequent responses.

  • $\begingroup$ I think the question might be more about the energy light provides plants during photosynthesis, so they can convert carbon dioxide & water into sugar & oxygen. $\endgroup$

  • $\begingroup$ Found this to add to the debate > key on the properties of photons what they can and can't do, in particular > "-They can have interactions with other particles such as electrons, such as the Compton effect. -They can be destroyed or created by many natural processes, for instance when radiation is absorbed or emitted." zmescience.com/science/what-is-photon-definition-04322 Does this affect your comment above ^ ? $\endgroup$ Commented Dec 27, 2019 at 17:51
  • $\begingroup$ Energy can’t be created or destroyed, it can only be transformed. Photons travel at 300,000 Km/sec. E=mc2. $\endgroup$
