Why are equatorial areas equal in size to earths polar regions heated much more intensely by the sun?

Equatorial areas receive more direct sunlight throughout the year compared to polar regions, which receive sunlight at a more oblique angle. This direct exposure results in greater solar energy concentration in the tropics. Additionally, the atmosphere has a thinner layer to penetrate in equatorial regions, allowing more solar radiation to reach the surface. Conversely, polar regions experience prolonged periods of low sun angles and greater reflection, leading to cooler temperatures.
