Explanation:


When a ship sails away from the shore, it appears to go down slowly and gradually. This happens because of the curvature of the Earth's surface. The Earth is round-shaped, and as the ship moves away from the shore, its bottom part disappears first, followed by the middle part, and eventually the top part. This happens because the Earth's surface curves downwards, and eventually, the ship goes below the horizon line.

Proof:


To understand this phenomenon, we can conduct a simple experiment. Take a basketball or any other round object and place a small object on top of it. Now, move the small object away from the center of the basketball. As you move it away, the object will appear to go down, and eventually, it will disappear from sight. This happens because the surface of the basketball curves downwards, just like the surface of the Earth.

Conclusion:


This observation proves that the Earth is round-shaped. If the Earth were flat, the entire ship would remain visible until it went out of sight. However, since the Earth is round, the curvature of its surface causes the ship to disappear gradually as it moves away from the shore.
