All of us from the school bench "drove" into the head that our planet is round, but we are forced to take our word for it. If you are told: provide evidence of the sphericity of the Earth, then many such a question will perplex. Even now, in 2017, there are many societies where people truly believe that our planet is flat and limited by glaciers, behind which unknown lands are hidden by us. As a rule, these people believe in conspiracy theory that they are all deceived and not divulged information under pain of death. They also put forward a lot of dubious evidence, which is based on unverified calculated data. So, our task in this work is to dispel all myths and give 5 evidence of the sphericity of the Earth. To check this, it is enough with the naked eye to look around and make sure many times that our planet is not flat with a probability of one hundred percent!
Proof 1. The Moon
The first evidence of the sphericity of the Earth was presented in the distant past by Aristotle, and it was built on a lunar eclipse. So, earlier people, since they were not educated, believed that our Moon is some kind of deity that plays with us like that. Some ancient Greeks were able to determine from the moon that our planet has the shape of a ball.
In addition, Aristotle was able to prove that in addition to the round shape, the Earth is also spherical. The evidence was elementary. Lunar eclipse - this is the moment when it is possible to see the shadow of our planet on the Moon by which it is easy to determine that the Earth has the shape of a ball.
Proof 2. Embankment
Try it yourself, provide evidence of the sphericity of the Earth by observing the ships. Many people like walking along the embankment, especially wonderful moments - this is a ship slowly rising above the water, it seems that it literally leaves the water. Why do you think this visual illusion occurs? Everything is very simple, this is another proof of a round planet.
Try an experiment, take an orange or any other round fruit or vegetable, and plant an ant on it. As he rises, he will slowly appear. If you plant the same ant on a flat surface, then it will look a little different, the ant will gradually materialize.
Proof 3. Stars
As in the case of the Moon, Aristotle made this discovery, observing the change of constellations, and a trip to Egypt helped him. Returning from his journey, he noticed that the constellations there and in the northern regions are very different, and this can only be explained by the fact that we are not looking at the sky from a flat surface.
Try to track this yourself and experimentally provide evidence of the sphericity of the Earth, because many, especially in the summer, go on trips, so spend this time with benefit for yourself. There is such a pattern - the further you move away from the equator, the more the constellations familiar to us go to the horizon.
Proof 4. Horizon
Try and give evidence of the sphericity of the Earth through observation. Just look into the distance, what do you see? And try to climb higher, what then will you see? This experiment is best done outside the urban area so that tall buildings do not interfere with your eyes.
In principle, this experiment is very similar to the second, where we watched the ships. The higher you climb, the more you will see, this is due to the fact that the Earth is not flat, if it were different, there would not be such an effect.
Proof 5. The Sun
If you have noon at the moment, then on the back of the planet is midnight. How can this be explained? The earth is round, if the planet were flat, and the Sun was a kind of spotlight, then we would have watched our star for many kilometers, even if we ourselves remained in the shade.
