Which heat transfer process explains why you feel warmth on a sunny day from the sun?

Explanation:
Radiation is the transfer of heat by electromagnetic waves. On a sunny day, the sun emits visible light and infrared radiation that travel through space and reach your skin and surroundings. When these rays are absorbed, their energy is converted to heat, so you feel warmth even without direct contact or moving air. Conduction would require touching a hot object to feel heat, while convection involves heat carried by moving air or liquid. Osmosis is about movement of water across a membrane and isn’t a heat transfer mechanism.
