state two evidence that proves the spherical shape of earth
Answers
Answer:
1. Watch a ship sail off to sea
2. Measure shadows across the country
Explanation:
1. Watch a ship sail off to sea
If you are able to watch a ship sail off to sea, watch its mast and flag as it fades off into the distance. You will notice that, in fact, it does not "fade off into the distance" at all; instead, you will see its mast and flag appear to slowly sink. The ship sailed beyond the point at which you would see it. Just to be sure, bring a pair of binoculars with you so that you can see even farther off into the distance.
2. Measure shadows across the country
On a flat Earth, the shadow that is cast by each would be of the same length. However, if you and your friend compare notes, you'll find that one shadow was longer than the other. That's because, due to the curvature of Earth, the sun will hit one part of Earth at one angle and another part of Earth at a different angle even at the same time of day.
