High latitudes receive less solar energy due to what factor?

The reason high latitudes receive less solar energy is primarily due to a lower angle of incidence. At higher latitudes, the sun's rays strike the Earth at a more oblique angle compared to the direct overhead sunlight received in lower latitudes. This oblique angle means that the same amount of solar energy is spread over a larger area, effectively reducing the amount of energy received per unit of surface area.

In contrast, areas near the equator receive sunlight more directly, resulting in greater concentration of solar energy and, consequently, warmer temperatures. Therefore, the lower angle of incidence in high latitudes is a significant factor contributing to the reduced solar energy they receive, making this the correct response. Other choices, such as temperature, humidity, and elevation, may influence local weather or climate but do not directly address the fundamental reason for lower solar energy reception at high latitudes.
