The correct explanation for the differences in the distribution of solar energy on Earth’s surface is: Earth’s curved shape and tilt on its axis do not allow the sun’s rays to fall evenly on its surface.
This is because the curvature of the Earth causes sunlight to strike different areas at varying angles, leading to differences in intensity and concentration of solar energy. Additionally, the tilt of the Earth's axis affects the angle of sunlight throughout the year, contributing to seasonal variations in solar energy distribution.
