(2.1) List some observational evidence that Earth is round.
The list of some observational evidence that the Earth is round.
Answer to Problem 1QFR
The shadow of Earth’s edge on the Moon during a lunar eclipse and different stars become visible when making travel from north to south.
Explanation of Solution
The following are the observational evidence that the Earth’s is round.
During the lunar eclipse, the edge of the Earth’s shadow on the Moon is always the portion of a circle and that shows the Earth is round.
When we make a journey from north to south, some stars that seen in the north become invisible and some that in the south become visible shows that the Earth is round in shape.
Conclusion:
Therefore, the list of evidence that the Earth is round is given is that the shadow of Earth’s edge on the Moon during a lunar eclipse and different stars become visible when making travel from north to south.
