Not really. They can't even see the entire Earth, because a sphere isn't fully visible from any perspective at any distance. It isn't a sphere anyway - it's an oblate spheroid.
how can you prove that earth is a sphere by looking at the pole st
we can prove that the earth rotates on its axis because we experience day time and night time/their is a change from day time to night time / night time to day time....
A boat at sea, alone, does not prove that is earth is round. However, boats can be used to prove that earth is round. This is because if the earth was flat, eventually a boat would sail to the end of earth and fall off the edge. This has never happened, so it can be inferred that the earth is round. Also, a boat can sail all the way around the world and end up right where it started, which proves that the earth is round.
The needs that led to the development of the artificial satellite and the transistor during the Cold War included the high unemployment of the Americans estimated then to be about 14 million, and the need to prove to the world that Americans were innovative.
Columbus did the most to prove the earth was shaped like a ball. He did this by sailing to America, and proving to Europe that the world was not flat. Edit: a lot of people think that, but it was established by the Ancient Greeks about 1800 years earlier.

An isochronous satellite is one that orbits the earth in one day. So it orbits the earth as the same speed as the earth rotates. Most satellites that are isochronous are infact geostationary satellites as they also stay in the same position above the earth. However these satellites occupy a very specific orbit above the equator. It is possible to have isochronous satellites that aren't geostationary however getting them to remain in orbit would prove difficult.
Given that we have satellite pictures of Earth now to prove that it's a sphere, you'd have to be willfully ignorant to believe it's anywhere other than about 6000 km below your feet.
Now you can look at pictures - in the old days you could watch ships disappear over the horizon.
By watching as the Earth also rotates from that view, you can see that the Earth is a rotating sphere and is not flat. Image by NASA. Like the other planets, the Earth is a sphere. It rotates around its own axis slowly but continuously, and completes this rotation about once every 24 hours.
that the earth is round just like what Magellan said ... `The church says the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in a shadow than in the church"
I can prove there are angels on earth.. trust in god and he will prove it to you too.
Columbus originally was determined to prove that
I have no Idea man. Or Girl, whatever you are. JK!! He sailed across the world with his crew and didn't fall of the earth, he went forward and back. Sorry about the start.
The rising and setting of the sun.
The earth is flat
