Question 1355Navigation General

The correct answer is A) increased obliquity of the Sun's diurnal circle. As the latitude increases, the Sun's diurnal circle becomes more oblique relative to the horizon. This means the Sun's path across the sky is at a more acute angle, resulting in a greater change in the length of the day between the summer and winter solstices. The other options are incorrect because they do not directly relate to the change in day length with increasing latitude.
