When you feel the warmth of the sun on your face what type of heat transfer are you experiencing?

It is known as Radiation. The Energy from the sun that warms up your face is a process called Radiation, because it WONT be convection because Convection only transfers through a Liquid or gas, and it WONT be conduction because for conduction to process you actually have to touch it and RADIATION IS YOUR ANSWER BECAUSE RADIATION IS THE PROCESS THAT MOVES THROUGH EMPTY SPACE.
