The energy Earth receives from the Sun comes from A. the mechanical motion of the planets orbiting the Sun. B. the burning of oxygen and carbon within the Sun's core. C. the burning of hydrogen and helium within the Sun's core. D. the mechanical motion of the Sun rotating around its axis.

Answer 1

The energy Earth receives from the Sun comes from C. the burning of hydrogen and helium within the Sun's core.

This process, known as nuclear fusion, occurs when hydrogen nuclei combine to form helium, releasing a tremendous amount of energy in the form of light and heat, which is emitted into space and reaches Earth.
