3.6 energy sources\nwhich source of energy is not related to the solar source?\n○ chemical\n○ gravitional\n○ nuclear\n○ radiation

Answer

Brief Explanations:

Chemical energy in fossil - fuels and biomass is related to solar energy as plants use sunlight for photosynthesis. Radiation from the sun is solar - related. Gravitational energy is mainly due to the gravitational force between celestial bodies and is not directly related to solar energy. Nuclear energy comes from nuclear reactions within atoms and is not related to the sun. But among the options, gravitational energy is more directly unrelated to the solar source as nuclear reactions in the sun are a different concept from the general nuclear energy we use on Earth which is from radioactive decay or fission of heavy elements.

Answer:

B. Gravitional
