Geography
You have gone from Delhi to Arunachal Pradesh on a study tour with your school during the winter vacation. As you woke up in the morning at 6 o'clock, you noticed the sun has risen whereas at Delhi sun rise is around 7.30 a.m. Similarly around 4.30 it was sunset while sunset is around 6 p.m. in Delhi. What do you think could be the reason for the sun rising and setting earlier than Delhi? Which feature of the earth can you relate to from this?
Answer
The sun rises from the east and sets in the west. Sunrise and sunset occurs at different times at different places because the earth rotates from west to east. Arunachal Pradesh is situated to the east of Delhi and hence, people in Arunachal Pradesh experience the sunrise and sunset earlier as compared to the people who live in Delhi.
This also proves that the earth is geoid in shape as had the earth been flat, the sunrise and sunset would have occurred at the same time all over the world.
