How do sailing ships provide evidence that the Earth is round?

Five ships commanded by Ferdinand Magellan left Spain and sailed southeast. They discovered a passage through the islands at the southern tip of South America, which is now called the Straits of Magellan. One ship was destroyed, and one returned to Spain. The remaining three ships then sailed northwest across the Pacific Ocean, and kept sailing west.
They sailed past many islands, always going mostly West. Magellan himself was killed in what were later named the Philippine Islands in the Battle of Mactan. The survivors continued west across the Indian ocean and around the Cape of Good Hope, and back to Spain. One ship out of five reached Spain, taking 3 years to complete the voyage.

Where do you find that the earth is spherical?
The Earth isn't actually perfectly spherical. It is slightly flattened at the poles. To find evidence of Earth's round shape, pictures taken from space are good secondary data to provide evidence.
Who founded the earth is round?
The idea of a round Earth appears to have originated in Greek Philosophy. Aristotle provided the first evidence of a round Earth, noting that explorers traveling south saw southern constellations rise higher above the horizon and that Earth cast a round shadow on the moon. Eratosthenes used the angle of sunlight at different latitudes to estimate Earth's circumference with surprising accuracy.
What evidence did Galileo provide for the support of a Heliocentric solar system?
Galileo did not directly provide evidence for the heliocentric principle but he did discover important evidence that raised doubts about the Ptolemaic system with the Earth at the centre. First, he discovered the moons of Jupiter, and these were the first objects discovered that definitely orbited round something that was not the Earth. That was one thing. Secondly, he discovered that Venus has a gibbous phase when seen from Earth in certain positions in its orbit. This is not explained by the Ptolemaic system because Venus cannot go round behind the Sun in the Ptolemaic system. Again this did not prove the heliocentric principle because Tycho Brahe came up with an intermediate system that had Mercury and Venus orbiting round the Sun, and then the Sun and the other planets orbit round the Earth. So this was still a geocentric system that explained all Venus's phases. Therefore Galileo did not have enough evidence to prove the heliocentric principle, and after his trial he recanted. But 60-70 years later enough new evidence had been gathered to convince most people that the Sun is at the centre, as we believe now.
The Muslims who discovered the world was round?
It was not discovered by Muslims,It was revealed to them through the Holy Quran that the earth is Egg-Shaped.Check 79:30 of Quran for evidence.
Who stated the earth was round?
Pythagoras stated the earth was round
How do sailing ships provide evidence thatearth is round?
Ships can circle the world by water and end in the spot where they began, proving the Earth must be round to the contrary belief that it was flat.
How has the space shuttle helped provide evidence that the earth is round?
because of pictures

How do observations of ships sailing out to sea support the idea of a round earth?
By the ships disappearing below the horizon
Which eclipse solar or lunar gives the evidence that the earth is round?
Lunar, because the Earth's shadow on the moon is always round, so the Earth must be spherical (round as seen from any angle)
What evidence did Lyell use to date the earth?
that the earth was round and big and it contained a force called the almighty gravity. How amazing LOL :)
Why is boat at sea evidence for a round earth?
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.

Who invented the first round-the-world sailing ship?

Did Columbus want to reach Asia by sailing west or reach Asia by sailing east or discover America or prove that the earth is round?
Columbus, and all educated Europeans of his time, already knew that the Earth was round. That required no voyage for proof. The trade routes to Asia via the east were controlled by the Turks (via land) and the Portuguese (for the sea route, so Columbus proposed sailing west to reach Asia. His problem was that his estimate of the size of the Earth was incorrect, so when he reached land in the Caribbean, and later on the American continent, he knew how far he had sailed and thought he had reached Asia.
What is the direct evidence that the world is round?
direct evidence there are pictures from space to prove that the world is round
