Question

Quizplus · Accepted Answer

The Sun's path on the sky for an observer on Earth is determined by his or her latitude or location on Earth. This is because the Earth rotates on an imaginary axis and this axis is tilted at an angle of 23.5° with respect to the plane of its orbit around the Sun. As a result, the Sun appears to rise and set at different points on the horizon throughout the year. The angle of the Sun's rays also changes throughout the day, and this is more pronounced at higher latitudes, where the Sun appears to rise and set at steeper angles, creating longer or shorter days throughout the year. Therefore, an observer's latitude is the primary factor determining the Sun's path on the sky.
