Question

1. How was it proved that the Earth is spherical in shape?​

Answer 1

Respuesta:

The earth is almost a sphere, and Eratosthenes saw it. Seleucus (c. 190 BC), who lived in the Seleucia region of the Tigris, established that the Earth is spherical (and in fact orbits the Sun), influenced by the heliocentric theory of Aristarchus of Samos.
