Question

give three evidences to prove that the Earth is spherical in shape​

Answer 1

Answer:

1) Circumnavigation of the earth : Ferdinand Megallian, a Spanish sailor with his crew sailed round the earth between 1519 and 1522, he and his crew were the first people to do so,

If the earth is flat, he and his crew would have fallen off the flat edge but instead they sail round the spherical edge because if the earth is truly flat, Ferdinand and his crew would have fell off the flat edge. Also modern air routes and area navigation are based on the assumption that the earth is spherical in shape

2)The circular horizon : when one view a distance horizon from the deck of a ship at a sea or from a cliff, the land and everywhere always look circular in shape with increase attitudes (height) which suggests that the earth is spherical in shape.

3) Sunrise and Sunset : As the earth rotates from west to east, place in the east experience the sun (earlier sunrise) than place in the west and also place in the west see the sun later (sunset) than place in the east.

If the earth is flat, then the whole earth should experience sunrise and sunset at the same time, but instead sun rise and set at different time for different place
