Sunlight warming the ground is an example of which heat transfer?

Explanation:
Sunlight warming the ground is heat transfer by radiation. Radiation is energy moving as electromagnetic waves that can travel through space and air. The Sun’s rays reach the ground and are absorbed, turning into heat in the surface. This differs from conduction, which needs direct contact between substances, and convection, which involves moving fluids carrying heat. It isn’t reflection, since the energy is absorbed and warms the ground rather than simply bouncing away.
