1. First of all, Columbus's first voyage expedition and voyage to America were of great significance in the history of geographical development.

Columbus and his party arrived at the two large islands of Cuba, Haiti and several small islands in the Indies in the middle of the eastern part of America, thus kicking off the discovery of the New World.

2. Secondly, Columbus's first voyage expedition and voyage to America are also of great significance in the history of navigation.

The voyage lasted more than 220 days, with a round trip of more than 8,000 nautical miles, a one-way trip of more than 4,000 nautical miles, and a cross-ocean voyage without sight of land for more than 30 days.

3. Columbus also discovered magnetic deviation during his first voyage and preliminarily measured the magnetic declination.

4. Columbus's first crossing of the Americas also played an important role in the history of colonialism.

5. Columbus's first voyage to the Americas was also of great significance in the history of agriculture and medicine.

Columbus and his party discovered tobacco, corn, potatoes, etc., important crops unique to the Americas for the first time; but they also spread the venereal disease syphilis from the Americas to Europe.

6. Columbus's maiden voyage also has a certain significance in the history of thought.

Columbus confirmed that there was indeed a legendary "golden age" and "good savages" in a "state of nature", which had an impact on early utopian socialism and the later Enlightenment.

7. The success of Columbus's first voyage stimulated Western European countries and people to compete for expeditions. Western Europe saw a climax of voyages, exploration, discovery, and colonization.

Extended information: The significance of Columbus's voyage and exploration: Columbus's first voyage and voyage to the Americas were of great significance in the history of geographical development.

Columbus and his party arrived at Cuba, Haiti and several small islands in the Indian Archipelago in the middle of the eastern part of America, thus opening the curtain on the discovery of the New World.

Columbus and his party opened up a new route from Europe across the Atlantic to the Americas and back safely, thus closely linking the Americas and Europe, and thus the New World and the Old World.

Columbus made more detailed records and descriptions of what he thought was the "West Indian Region", which gave people in the Old World a preliminary understanding of this place.

At this point, the geographical progress initiated by the Portuguese since the late Middle Ages has developed from quantitative change to qualitative change, from gradual evolution to leapfrog, thus beginning the great geographical discovery.

This is because the Canary, Madeira, Azores, Cape Verde and other islands previously discovered by the Portuguese (including other Europeans) are still islands in Africa and Europe, and are still attached to the Old World.

They are not springboards and stepping stones to the discovery of new lands.

The west coast of Africa and the southern tip of Africa that the Portuguese had previously discovered were unknown parts of Africa, not the edge of the New World or the New Continent.

The question of whether any civilized people in the Old World had been to the Americas before Columbus, including whether the Chinese, other Asians, Africans, Europeans, and even Oceanians had been there, is a matter worth studying.

Even if some people go, can they return, can they connect America with other continents, and can they leave more detailed records and descriptions so that people in the Old World can know and understand America.

Needless to say, the Norsemen of the Old World set out from Norway, Iceland and Greenland and briefly settled on the island of Newfoundland in northeastern North America in the late 10th and early 11th centuries, and in other places on the Atlantic coast of North America.

Logged in.

Among them, the red-haired Eric Neiego made a greater contribution to the discovery of Greenland.

Greenland was the name he gave it, which means Greenland.

"His son Lev, who was lucky, made a greater contribution to the discovery of Newfoundland. He called it "Vinland", which means Vineland in one word and fertile land in another." However, Northern Europe

The Columbus-style discovery was an accidental, interrupted, and unsuccessored geographical discovery, while the Columbus-style discovery was a planned, continuous, and successive geographical discovery.

Therefore, the great geographical discovery began in 1492 when Columbus discovered America.
