"The World is Round"

"The World is Round" refers to the Earth's shape, which is approximately spherical. This concept, established through centuries of observation and scientific inquiry, explains phenomena such as the curvature of the horizon, the way ships disappear hull-first when sailing away, and the variations in star visibility from different latitudes. The Earth's roundness is also crucial for understanding time zones, climate patterns, and navigation. While it's often represented as a perfect sphere, the Earth is slightly flattened at the poles and bulging at the equator, making it an oblate spheroid.
