Answer:
Meera can ask her teacher the following questions:
- Why does the Sun look like it moves across the sky?
- Does the Sun really move, or is it the Earth moving?
Question 3.
Figure it out
Suppose you stand at the same spot during the morning and the afternoon. In the morning, your shadow points in one direction, while in the afternoon it points in another. Why? Would the length of your shadow be the same at both times?
Answer:
- In the morning, the Sun is in the east, so the shadow points west. In the afternoon, the Sun is in the west, so the shadow points east. The direction changes because the Sun’s position changes.
- The shadow’s length is not the same. In the morning, the shadow is longer because the Sun is low. In the afternoon, the shadow is shorter when the Sun is higher, but it gets longer again as the Sun sets.
