Question 1507Navigation General70% to pass
The change in the length of day becomes greater as latitude increases because of the _______________.
AI Explanation
The correct answer is C) increased obliquity of the celestial sphere.
As the latitude increases, the celestial sphere becomes more oblique (tilted) relative to the horizon. This increased obliquity results in a greater change in the length of day, as the sun spends more or less time above the horizon at higher latitudes.
The other options are incorrect because they do not directly explain the relationship between latitude and the change in day length. Option A refers to the distance between the Earth and the sun, which does not significantly impact the change in day length. Option B is related to the diurnal circle, but does not explain the effect of latitude. Option D refers to the distance between terrestrial meridians, which is not the primary factor affecting the change in day length.
