The transformation relating to energy is illustrated by the process of light being converted to heat by radiating surfaces. This option highlights a fundamental energy transformation; specifically, it describes the conversion of electromagnetic energy (light) into thermal energy (heat). When light strikes an object, such as a surface, some of that energy is absorbed, causing the temperature of the surface to increase, which is essentially a transformation from one form of energy to another.

In contrast, the other options represent different processes that do not focus on energy transformations specifically. For example, the movement of water in a stream involves kinetic energy but doesn’t emphasize the conversion of energy from one form to another. Food chains show the flow and transfer of energy across different trophic levels, but they focus more on the transfer rather than the transformation. Soil formation from mineral deposits involves geological processes, but it does not address energy changes directly. Therefore, the selected answer effectively encapsulates the concept of energy transformation.
