Interesting to point out the common myth of seasons being caused by the variation in distance between Earth and the Sun over the year. Rather than the distance, it is actually the amount of time exposed to sunlight that dictates seasons. Due to the tilt of Earth, the length of day time differs between the two hemisphere. If one were to draw a band along the longitude of his location and imagine sunlight splitting Earth perfectly vertically where one half is bright and the other dark, we can see that the proportion of the band that is bright will change as you walk across the latitude lines.

Does the tilt of the Earth also change the irradiance that a place on Earth receives as well? Or is it mostly because of the length of day.
