Advancements in maritime technology during the Age of Discovery (1400s-1500s) primarily included:
-
Development of advanced cartography techniques: This allowed explorers to create more accurate maps, which helped them navigate uncharted territories and improved their understanding of global geography. Accurate charts were essential for long-distance sea travel, enabling explorers to find routes to new lands and ports.
-
Introduction of the magnetic compass: Although not listed in your options, the magnetic compass was a crucial advancement during this time. It enabled sailors to determine direction accurately, even when landmarks were not visible, enhancing navigation across open waters.
While the other options (steam engine, printing press, and telegraph) were important in their own contexts, they were not central to the maritime advancements specific to the Age of Discovery. The steam engine developed later and the printing press aided in disseminating knowledge but did not directly influence maritime exploration practices of this period. The telegraph also came into use after this era.
