If the Earth's rotation axis were tilted slightly so that the poles were pointed more squarely at the Sun, the days would generally get longer for people living near either of the Earth's poles.
To understand why, let's consider the effects of the tilt on the polar regions. Currently, the Earth's axis is tilted at about 23.5 degrees relative to its orbital plane around the Sun. This tilt is the reason we have seasons, as different parts of the Earth receive varying amounts of sunlight throughout the year.
If the tilt were increased so that the poles were more squarely pointed at the Sun, it would mean that the polar regions would experience more direct sunlight for a longer duration during the day. This would lead to extended daylight hours, resulting in longer days.
However, it's important to note that the actual effects on daylight hours would depend on the magnitude of the tilt change and the specific time of year. For example, during summer solstice in the Northern Hemisphere, when the North Pole is tilted towards the Sun, the days are already long. If the tilt were increased, it could lead to even longer daylight hours. On the other hand, during winter solstice, the days are already short, and increasing the tilt may make them even shorter.
Overall, changing the tilt of the Earth's rotation axis would impact the length of days for people near the poles, but the specific changes would depend on the time of year and the magnitude of the tilt change.
