Because people have seen it from space and anyway if the Earth was flat all the water would fall of the edge so then we would not survive
The earth is not flat because there is overwhelming evidence from science, including satellite images, GPS technology, and the way ships disappear over the horizon, that clearly demonstrates the earth is a spherical shape. Additionally, the laws of physics and gravity support the idea of a spherical earth.
Projection
Cartographers an represent the spherical Earth on flat paper by making a projection, which is like casting shadows from the spherical world onto a flat piece of paper.
Yes earth is a spherical (round), thousands of years ago people did not know that planet earth was round, they just thought it was flat so if they went to far they would fall of the edge! but nowadays because of spacetravel etc, we have seen planet earth and they have noticed it was a spherical planet. So yes it is.
They thought that the Earth was flat and not spherical.
The main theories about the shape of the Earth are the spherical Earth theory, which posits that the Earth is a sphere, and the flat Earth theory, which incorrectly suggests that the Earth is flat. The spherical Earth theory is supported by scientific evidence such as images of the Earth from space and the way ships disappear over the horizon.
Cuz it's flat, dummy
If the Earth were to become flat, this would go against the well-established scientific understanding of its spherical shape. If such a drastic change were to occur, it would likely have profound and catastrophic effects on our planet's geology, atmosphere, and ecosystems. Additionally, the laws of physics and gravity as we know them would be completely disrupted.
It is a drawing of the earth on a flat surface
because there has to be some kind of distortion of earths spherical shape
They actually didn't. Flat Earth is a myth. The spherical Earth has been a scientifically established fact since long before Ptolemy.
Since the determination of the fact that Earth is spherical as opposed to flat, all scientists (after a short lag period) have accepted that it is so.
