Hydro: Helps in the hydrological cycle of evaporation, condensation & precipitation. This results in a much more even distribution of water over the world.
Atmo: Helps in the rising of air masses and air parcels. Also Contributes to the movement of warm air particles from equator to the poles through more intensive heating at the equators.
Litho: I dunno… But it sure doesn’t help move the plates, nor does it helps volcano eruptions…
Bio: Keeps animals and plants from dying of cold, form of energy that provides food for plants and eventually the whole of the food chain, provide light for animals to see, etc etc… even photography and film relys on it, so go figure…
