Why the day gets longer and shorter in Rostov-on-Don
Earth's axis is tilted about 23.4 degrees, so as the planet orbits the Sun, Rostov-on-Don leans toward the Sun for part of the year and away for the rest. When it leans toward the Sun the days lengthen and the Sun climbs higher; half a year later the opposite happens. The size of the swing depends on how far Rostov-on-Don sits from the equator: the further away, the bigger the difference between the longest and shortest day.
