TOP 10 REASONS Why We Know the Earth is Round

The video explains various proofs of Earth's roundness, including time zones, the Coriolis effect, and spherical geometry. It discusses how the sun's position and star visibility change with latitude, and how circumnavigation and horizon observations support a spherical Earth. The video concludes with evidence from lunar eclipses and photographs.
