Leo nimekuja na swali langu kwa wana JF wale wa Earth is around, ninataka mnipe jibu la swali langu JE DUNIA NI DUARA..!?
Kama dunia duara kitendo hiki kinaitwaje au kinaeababishwa na nini..!?
Je dunia inazunguluka kama inazunguluka inakuwaje mpaka kikatokea kitendo hiki..!?
Je shuleni uliwai kufundishwa juu ya kitendo hiki..!?
Mwisho kabisa kama Dunia sio duara unazani ni kwa sababu gani ukweli huu wa dunia kuwa sio duara unafichwa sana unazani una manufaa gani kwa wanaouficha au wanauficha kwa sababu gani..!?
Aya JF (HIGH IQ) tupieni madini.

Below are the simplest reasons that prove that the Earth is round.
It turns out that we can test many of these reasons out for ourselves, too.
• If the Earth was flat, we would be able to look out and see very far, assuming that there were no buildings in the way. We could see another city that’s hundreds of miles away. Or a ship sailing out to sea. The boat would stay in view no matter how far out to sea it went.
However, if we look out when standing on the ground, we can’t see that far. We can’t look out into the distance and see a town that’s miles away. And a ship will slowly start to disappear from view as it gets farther away. This is because the Earth is round. Things in the distance are not visible because there is a curve to the landscape.
One way to test this is to watch the sunset. Find a spot where you can see the sunset, and also have a place close by where you can safely move higher, such as a tree or building. Or even start laying down and then stand up. On the ground, the sun will eventually disappear beyond the horizon. When this happens, quickly go to your higher spot. From there, you’ll be able to see the sun again for a brief time.
• You have probably seen that when the sun is out, it causes a shadow to form if it hits something. It turns out that we can use shadows as another piece of evidence that the Earth is round.
The fact that the sun sets at different times in different locations lets us know that the Earth is a sphere. Image by NASA.
If the Earth were flat, then shadows would be the same length, regardless of location. This would mean that the sun is hitting all places on Earth at the same angle, resulting in the same shadow. However, it turns out that this is not the case. If we were to place two identical sticks in the ground in two different places on Earth, we’d find that the length of their shadows differs. This is because the Earth is round, and so the way the sun hits each location will be a bit different.
• During a lunar eclipse, the Earth passes between the moon and the sun. When that happens, the sun projects Earth’s shadow onto the moon. When this happens, you can actually see the Earth’s shadow if you look up at the moon. If you do this, you’ll see that there is a round shadow, not a flat one.
A follow-up question might be whether the Earth could be flat and round, like a pancake. This would cause the shadow on the moon to be round, but the shape of the Earth to be flat. If the Earth were flat but rotating, its shape would be different for eclipses at different times of the day or night. Sometimes it would appear only as a line. The rest of the time it would appear like an oval or circle as it’s spinning. However, we know that the shadow the Earth casts on the moon during an eclipse has always been circular, regardless of time of day. This supports the idea that the Earth is a sphere.
These are just a few testable ways we know that the Earth is round.
You can also think of other ways that show the Earth is round and not flat
