What impact does the sun's position have on shadow length?

The position of the sun significantly influences the length of shadows. When the sun is higher in the sky, which occurs around noon, it casts light at a steeper angle. This results in shadows being shorter since the angle of incidence is more direct. Conversely, when the sun is lower on the horizon, such as during sunrise and sunset, shadows are cast at a more obtuse angle, leading to longer shadows. This relationship between the sun's elevation and shadow length is a fundamental concept in understanding how light interacts with objects on Earth. The correct choice highlights this direct correlation, affirming that the higher the sun's position, the shorter the resulting shadow becomes.
