Eli5 Why does the “directness” of sunlight change its heating effect

375 views

Bill nye says our change in seasons is largely due to the fact that the directness of the sunlight hitting a given place changes due to the earths tilt and position in its orbit.

Why does the directness of light create more heat (hitting at equator for example), while glancing light rays (hitting antarctica) produce less heat?

Sunlight coming at an angle has to travel through more atmosphere before it reaches the ground where it “loses” more energy on its way there. (Obviously energy is never lost)

Also obviously longer/shorter days have an impact on how much the surface can heat up/cool down.
