Question

how does solar energy reach the surface of earth?

○ through dust and particles

○ through convection

○ through conduction

○ through radiation

Explanation:

Solar energy travels through the vacuum of space to Earth. Conduction and convection require matter (solids/fluids) to transfer heat, which is absent in space. Dust/particles are not the primary transfer mechanism. Radiation (electromagnetic waves) is the only way energy moves through a vacuum.

Answer:

through radiation
