The Shape of the Earth

The earth is spherical in shape. Reasons which prove that the Earth is spherical in shape are as follows

During a lunar eclipse, the shadow of the Earth falls on the surface of the Moon. This shadow is visible as an arc of a circle. Because the shadow always appears spherical, we know that the Earth is spherical.

The Pole Star can be observed at an angle of 90° in the sky at the North Pole. If we travel southwards, the angle of the Pole Star decreases, and at the Equator, the angle becomes zero. This proves that the path of travel is an arc of a circle.

Because all the planets and the Moon appear spherical, we can conclude that the Earth too is spherical. The pictures of the Earth taken from space prove that the Earth is a sphere.
