Is the EARTH flat or round? really deep question don't make fun of it cuz there are too many contradiction
suter [353]

Answer:

Round

Explanation:

The Earth is round ,even though there are many contradictions. The Earth spins on an axis, which is why there are different time zones all around the world. If the world was flat, then an Earth's core wouldn't exist and also the laws of gravity would not make since due to the Earth being considered flat. People would never know if they met the end of the Earth, or if they walked off the face of the Earth. Also note that if the Earth was flat then our Solar System would have to be flat since it involves the planets to revolve around the Sun.
