The sun's light travels ninty-three million miles to reach the Earth.

A. CONVECTION B. RADIATION C. CONDUCTION

traveling through a vacuum (outer space), kind of rules out convection and conduction

The answer to the question is B. RADIATION.

Radiation is the process by which energy is transferred in the form of electromagnetic waves. In this case, the sun's light energy is transferred to the Earth through radiation.

To arrive at this answer, you can use the knowledge of how sunlight reaches the Earth. The distance between the Sun and the Earth is approximately 93 million miles (or about 150 million kilometers). This vast distance makes it unlikely that the transfer of energy occurs through conduction or convection.

Conduction is the transfer of energy through direct contact between particles. In this scenario, there is no direct contact between the Sun and the Earth, so conduction is not the correct answer.

Convection is the transfer of energy through the movement of fluids or gases. While convection does occur within the Sun itself, with hot gases rising and cool gases sinking, it does not explain the transfer of energy over the vast distance between the Sun and the Earth.

Therefore, the correct answer is radiation, as it involves the transfer of energy through electromagnetic waves, which is how sunlight travels from the Sun to the Earth.
