Question

Quizplus · Accepted Answer

The primary thermal energy transfer mechanism that warms Earth from the Sun is through radiation. The Sun emits electromagnetic radiation (including visible light) that travels through space and is absorbed by Earth's atmosphere and surface, thus heating the planet. Convection and conduction also contribute to heat transfer on Earth, but they are not the primary mechanism by which Earth is warmed by the Sun.
