Question

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

Explanation:

• Radiation: It is the transfer of energy in the form of electromagnetic waves (like light, heat in the form of infrared). The space between the Sun and Earth is mostly a vacuum. Electromagnetic waves can travel through a vacuum.
• Convection: Requires a fluid (liquid or gas) medium. Since there is no significant fluid medium (in the sense of a continuous, dense fluid like in a pot of boiling water) between the Sun and Earth, convection is not the way.
• Conduction: Needs direct contact between particles. There is no such direct - particle - to - particle contact over the vast distance from the Sun to Earth.
• Movement of particles: Similar to conduction and convection in the sense that it implies a more "material - based" (particles in a medium like a solid, liquid, or dense gas) transfer. But again, the space between Sun and Earth is a near - vacuum.

Answer:

through radiation
