Problem
Which mechanism most directly accounts for energy traveling from the Sun to Earth across the vacuum of space?
(a) Evaporation, because the solar wind removes energetic particles that then warm Earth
(b) Radiation, because electromagnetic waves can propagate without a material medium
(c) Conduction, because energetic particles collide and pass energy through space
(d) Convection, because hot plasma circulates through space toward Earth
