Question 1 Report

Which of the following explains the variation in the lengths of day and night with the seasons?

Answer Details
The variation in the lengths of day and night with the seasons is explained by the inclination of the earth. This is because the earth's axis is tilted at an angle of 23.5 degrees relative to the plane of its orbit around the sun. As the earth revolves around the sun, different parts of the earth receive varying amounts of solar radiation, causing the seasons. When one hemisphere is tilted towards the sun, it receives more direct sunlight and experiences longer days and shorter nights, while the other hemisphere experiences shorter days and longer nights. As the earth continues its orbit, the hemispheres switch positions, causing the seasons to change.
