What describes the warming of the Earth through energy coming from the sun?

• A. Conduction
• B. Convection
• C. Radiation
• D. Evaporative Cooling

Answer: (C)

The warming of the Earth through energy coming from the sun is described as radiation. This process involves the transfer of energy in the form of electromagnetic waves. The sun emits energy that travels through the vacuum of space, reaching the Earth and warming its surface. This transfer of energy can occur without the need for a medium, which is characteristic of radiative heat transfer. In contrast, conduction involves the direct transfer of heat through contact between materials, while convection involves the movement of heat via fluids (liquids or gases) due to temperature differences. Evaporative cooling relates to the cooling effect that occurs when liquid turns into vapor, and does not describe the warming process initiated by solar radiation. Thus, radiation is the correct term for the warming effect of solar energy on Earth.
