Explain in 1 or 2 sentences
(1) what physical process allows geothermal energy to keep a house warm and (2) whether geothermal energy could be considered a form of solar energy.
(1) Geothermal energy utilizes heat from the Earth's core that is transferred to the surface through the process of conduction, helping to keep a house warm.
(2) Geothermal energy is not considered a form of solar energy, as it comes from the Earth's internal heat rather than from the sun's radiation.
