How the shape of the land causes some places to receive more solar radiation than others?

The curvature of the Earth affects the angle at which sunlight hits different regions, leading to variations in solar radiation. Mountain ranges can create rain shadows, where one side receives more sunlight and the other side receives less due to the blocking effect of the mountains. Landforms like valleys and slopes can also influence the distribution of solar radiation by altering the orientation of the surface to the sun.
