Final answer:
Convection is a form of heat transfer involving physical movement and does not directly affect solar radiation; the correct processes influencing solar radiation are reflection, absorption, and scattering.
Step-by-step explanation:
The question concerns the interaction of solar radiation with Earth's atmosphere and which process described does not occur to solar radiation. When solar radiation reaches our atmosphere, it can undergo various interactions, namely reflection, absorption, and scattering. However, convection is not a process that directly affects solar radiation as it travels through the atmosphere, because convection is a form of heat transfer involving the physical movement of air or liquid, and it doesn't act on the radiation itself. On the other hand, reflection, absorption, and scattering involve the redirection or absorption of the radiation's energy by atmospheric particles and gases.
