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

385 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?

The simplest way to put this is just that it’s the same amount of light spread out across a larger area.

Hold a flashlight 2 feet from the wall, and point it straight at the wall. Then, tilt the light to an angle. More of the wall is illuminated, but the light didn’t get any more powerful.

That’s because the light is now more spread out.
