Stepwise Answers, Diagrams, and Exam Tips for Class 7 Science Earth, Moon, and Sun

2. Answer the following questions in about 30 words.


1. Rashmika saw that coconut tree shadows were long in the morning and shorter in the afternoon. What does this observation tell us about the movement of the Sun and the Earth?


Answer: Rashmika’s observation shows that the Sun appears to move across the sky from East to West. However, it is actually the Earth’s rotation on its axis that causes the changing positions of the Sun and the varying lengths of shadows during the day.


2. What causes the Sun to rise in the East and set in the West?


Answer: The Sun rises in the East and sets in the West because the Earth rotates from West to East on its axis. This rotation makes the Sun appear to move across the sky each day.


3. What did you learn from Activity 12.1 using a merry-go-round?


Answer: Activity 12.1 shows that while sitting on a rotating merry-go-round, stationary surroundings appear to move in the opposite direction. Similarly, as Earth rotates, objects like the Sun, Moon, and stars appear to move across the sky.
