Original AI Prompt
Generate & Play Hailuo AI video：The phenomenon of day and night length variation by season on Earth: - As Earth orbits around the Sun, it sometimes tilts half of its northern hemisphere towards the Sun, and sometimes tilts half of its southern hemisphere towards the Sun: + On the summer solstice (22-6), the northern hemisphere is tilted towards the Sun, thus receiving more sunlight and heat, while the southern hemisphere is the opposite. + On the winter solstice (22-12), the southern hemisphere is tilted towards the Sun, thus receiving more sunlight and heat, while the northern hemisphere is the opposite. - Because the line dividing day and night does not coincide with Earth's axis, locations in the northern and southern hemispheres experience different lengths of day and night according to their latitude. - The phenomenon of day and night length variation at different latitudes becomes more pronounced as one moves away from the equator towards the two poles. - On the two equinoxes (21-3 and 23-9), at noon, the Sun's rays strike the Earth perpendicularly at the equator. Both hemispheres are equally illuminated.
