Final answer:
Advances in sailing technology and experience in the Atlantic Islands in Africa paved the way for Columbus' discovery of America. His journey was a product of the efforts of many people, including King Ferdinand and Queen Isabella of Spain. Navigational problems that affected all sailors in the Atlantic world included the lack of accurate maps and charts and unpredictable weather conditions.
Step-by-step explanation:
The advances in sailing technology and experience in the Atlantic Islands in Africa played a significant role in paving the way for Columbus' discovery of America. Prior to Columbus, Portuguese explorers had already navigated around the southern tip of Africa, opening up new maritime routes. This knowledge of wind patterns, currents, and navigation techniques allowed Columbus to plan his journey and make successful transatlantic voyages.
Columbus's journey was also a product of the efforts of many people. He secured funding and support from King Ferdinand and Queen Isabella of Spain. The Spanish monarchy, along with their advisors and navigators, provided the resources and knowledge that Columbus needed for his expeditions. Without their support, Columbus may not have been able to make his voyages.
Despite these advances, there were still navigational problems that affected all sailors in the Atlantic world. One of the biggest challenges was the lack of accurate maps and charts. Sailors had to rely on imperfect and incomplete knowledge of the ocean and coastlines. Additionally, unpredictable weather conditions, such as storms and hurricanes, posed a constant danger to sailors. These navigational problems made transatlantic voyages risky and uncertain.
