Question

how does energy from the sun travel to earth?
through radiation
through convection
through conduction
through the movement of particles

Explanation:

Space is nearly a vacuum with no particles for conduction or convection (which require a medium of particles). Solar energy travels to Earth via electromagnetic radiation, which can propagate through empty space. Conduction and convection rely on particle movement, which is not possible in the near-vacuum between the Sun and Earth.

Answer:

through radiation
