Answer 2

The fact that the Earth is round has been proven countless times by many scientists all over the world. Everyday observations can also indicate this shape, some of which have been given below.

• Observations and experiments of intellectuals more than a thousand years ago have established the presence of a curvature to the surface of the planet. They have all come to the conclusion that the Earth is indeed round
• One may choose to observe the shape of the horizon at a distance. Ships, the sun, and other moving structures seem to dip into the horizon and disappear into it. This phenomenon is possible only as the Earth is round
• The shadow that the Earth casts on the surface of a moon during a lunar eclipse is always round, hinting at the shape of the Earth
