Earth receives energy from the Sun primarily through which method of heat transfer?

• A. Evaporation
• B. Conduction
• C. Radiation
• D. Convection

Answer: (C)

Verified step by step guidance

1. Identify the three main methods of heat transfer: conduction, convection, and radiation.
2. Understand that conduction requires direct contact between materials for heat transfer to occur.
3. Recognize that convection involves the movement of fluids (liquids or gases) to transfer heat.
4. Recall that radiation is the transfer of energy through electromagnetic waves and does not require a medium.
5. Since space is a vacuum and Earth receives energy from the Sun across this vacuum, the primary method of heat transfer is radiation.
