Question

Under which condition would time periods of daylight and darkness be equal everywhere on Earth all year? A. if Earth revolved around the sun in a more circular orbit B. if Earth rotated on an axis that was not tilted with respect to Earth's orbit C. if Earth had two moons D. if Earth revolved in an orbit closer to the sun

Answer 1

The correct answer is
B. if Earth rotated on an axis that was not tilted with respect to Earth's orbit 

In fact, the fact that Earth's axis is tilted is the reason why the durations of day and night are different in every part of the Earth. If the axis was not tilted, we would have exactly 12 hours of day and night in every point of the Earth, for the whole year.

Answer: The correct Answer is B.
