Which heat transfer method enables the Sun to warm Earth, despite the vast empty space between them?
Radiation
Radiation is the heat transfer method that allows the Sun to warm the Earth, since it can travel through the vacuum of space without needing a medium.
Conduction and Convection both require a physical medium to transfer heat, and Insulation is a method of resisting heat transfer, not a transfer method itself.
Hence, Radiation is the correct answer.
