The correct answer is option 1: At the Equator. At the Equator, the duration of day and night is almost equal throughout the year. This is because the Earth`s axis is tilted at an angle of about 23.5 degrees, and this tilt causes the different seasons and varying lengths of day and night at different latitudes. At the Equator, the tilt has the least effect, resulting in a more equal division of day and night. This phenomenon is known as the equinox, which occurs twice a year (around March 21st and September 21st). During these times, the length of day and night is approximately 12 hours each. It is important to note that the durations of day and night become less equal as you move towards the poles, resulting in areas experiencing continuous daylight or darkness during certain times of the year.
