4. Why does the appearance of the moon change?
Ans. The appearance of the moon changes due to its position relative to the sun and the Earth. As the moon orbits the Earth, different portions of its surface are illuminated by the sun, leading to different phases such as a new moon, crescent moon, half moon, and full moon.
5. What causes changes in the length of day and night?
Ans. Changes in the length of day and night are caused by the tilt of the Earth's axis and its orbit around the sun.
