Earth's curved shape and tilt on its axis play a significant role in the distribution of solar energy on its surface. Due to the Earth's spherical shape, the sun's rays hit the equator more directly, resulting in higher solar energy absorption in these regions. Areas closer to the poles receive less direct sunlight, leading to lower solar energy absorption. Additionally, Earth's tilt on its axis causes variations in the angle at which solar radiation hits the surface, further influencing the distribution of solar energy across different regions. Other factors such as clouds, atmospheric conditions, and surface reflectivity also affect the distribution of solar energy on Earth's surface.
