प्रश्न
Provide reliable evidence to prove that the earth is spherical in shape.
उत्तर
The earth can be clearly seen spherical in the photographs from the satellite. Other proofs are the sight of the mast of a ship first before the ship appears, varying heights of the poles fired at different places at an interval of 5 km, through the Bedford Level Experiment and the sight of Pole Star at 90° from the North Pole and the view of the earth’s horizon as a circular from higher altitudes.
