During Magellan s voyage, the southernmost point he reached was located

Strait of Magellan.

At the end of August 1520, the fleet sailed out of the port of San Juan and continued its voyage south along the Atlantic coast, preparing to find a strait to the "South Seas". After three days of sailing, at 52 ° south latitude, a bay was discovered. Magellan sent two ships to investigate, hoping to identify the waterways leading to the "South China Sea".

That night there was a storm, roaring, huge waves, and the ship sent to it was in danger of hitting the cliff and sinking at any moment, and this emergency lasted for two days. Coincidentally, at this moment of sudden change, they found a gorge leading to the "South China Sea", which is later known as the Strait of Magellan.

Magellan led a fleet along the Strait of Magellan. The gorge is curved, sometimes wide and sometimes narrow, and the peaks on both sides of the bank are towering, unpredictable. The indigenous people on both sides of the strait rejoiced in the bonfires, the blue smoke wisps of the day, and the night was bright, like a guard of honor specially arranged for Magellan's arrival.

Magellan was so overjoyed that he saw the land on fire at night, and named the land on the southern shore of the strait "Tierra del Fuego", which is the island of Tierra del Fuego in present-day Chile.

After more than 20 days of arduous and circuitous sailing, we finally arrived at the west entrance of the strait and walked out of the Strait of Magellan. Later, after two months of patrolling around in five directions in search of small islands or land, the "San Antonio", which was loaded with the most food, escaped and returned to Spain.

Chile and Argentina at the southern tip of South America jointly own a strait, which is now named the Strait of Magellan in honor of Magellan.

The reason Magellan sailed to prove that the Earth was round was because his fleet rounded one of the Earth's meridians and eventually returned to the point of departure. When they returned, the constellations and astronomical culture of their ships had also changed, suggesting that they had sailed in a large circle rather than a straight line. In addition, when they sailed to 54 degrees south latitude, they also saw ice in the Antarctic region, which proves that there is a South Pole on Earth.

These observations and data all prove that the Earth is round.

Magellan's voyages proved that the earth is round. Since ancient times, there has been a lot of evidence that the earth is round, such as the phenomenon of it disappearing below the horizon when ships are getting farther and farther away; Or when the sun rises and sets, people see different times in different positions on the earth. These phenomena all indicate that the earth is round.

In addition, there is some more scientific evidence, such as gravity and astronomical theories, among others.

In addition, from a historical point of view, there are some ancient scholars and scientists who have put forward the theory that the earth is round, such as Aristotle and Ptolemy in ancient Greece. They used different methods of observation and experiments to prove that the Earth is round. It was these early scientists who pioneered the development of modern scientific theories and made significant contributions to mankind's understanding of the world.

Overall, Magellan's voyage was a key event in proving that the Earth was round. Through his dry and wide voyages, people began to gain a deeper understanding of the shape and size of the Earth, which also laid the foundation for later fields of geography and astronomy. <>

Zheng He made seven voyages to the West from 1403 to 1405, passing through Java, Sumatra, Ceylon, Cochin on the west coast of India, and as far as the eastern coast of Africa (to today's Red Sea).

Columbus – Departed from Puerto Barros, Spain, on August 3, 1492, and returned to Spain in March of the following year. The main seafaring achievement was the discovery of the American continent.

Magellan set sail on September 20, 1519, on a voyage around the world, but died in tribal fighting in the Philippines. Later, 19 crew members returned to Europe.

Magellan's nautical route can prove that the earth is round. Magellan was a Portuguese navigator who, in the 16th century, managed to circumnavigate the earth for the first time, proving that the earth was round, high, rather than flat.

Through Magellan's voyage, one can clearly see that as he circumnavigated the Earth, he always kept moving in one direction. This shows that the earth is flat, because if the earth is flat, it will fall from a certain direction at some point. Also, as he circumnavigated the southern tip of South America, he noticed that the sun was in a different position than before.

This also proves that the earth is round because the position of the sun is constantly changing on the earth.

In addition to this, Magellan's voyage also indicates the size and shape of the earth. His fleet circumnavigated the area south of the Earth's equator, which indicates that the Earth's equator is very large and that the vast oceans are very deep.

Overall, Magellan's nautical facts do prove that the Earth is round. This fact shows the true shape of the Earth through the invariance of its direction of travel, the change in the position of the Sun, and the fact that its fleet goes around the area south of the Earth's equator. This discovery fundamentally changed the way people think about the planet, having a significant impact on many aspects of global navigation and exploration, and this fundamental idea is now widely accepted.

In September 1519, the navigator Magellan led an expedition fleet of more than 200 people, divided into five sailing ships from Spain, from west to east across the Atlantic, Pacific and Indian Oceans, and finally returned to the Atlantic, and finally returned to the original place of departure in September 1522 The first complete slippage of Magellan's ship Xinwang Ridge sailed around the earth, proving that the earth is a sphere

So the answer is: from west to east; Atlantic Ocean; Pacific Ocean; Indian Ocean; It proves that the earth is a sphere
