how does energy from nuclear fusion in the suns core eventually reach earth?\nthrough conduction\nvia solar wind\nas radiation\nby convection
Answer
Brief Explanations:
- Conduction requires direct contact between particles, which is not feasible between the Sun and Earth as they are separated by space.
- Solar wind consists of charged particles (mostly electrons and protons) and while it has its own effects (like influencing Earth's magnetosphere), it is not the main way energy from the Sun's core reaches Earth.
- Radiation is the transfer of energy in the form of electromagnetic waves (such as light - which is a form of electromagnetic radiation). The Sun emits energy in the form of electromagnetic radiation (including visible light, infrared, ultraviolet etc.) which travels through the vacuum of space to reach Earth.
- Convection is the transfer of heat through the movement of a fluid (liquid or gas). There is no fluid medium (in the sense of a continuous medium like in a pot of boiling water) between the Sun and Earth for convection to occur in the traditional sense.
Answer:
As radiation.
