What were two navigation tools used by explorers?
Exploration has always been a testament to human curiosity and ingenuity. Throughout history, explorers have utilized various tools to navigate the vast and often treacherous seas. Two of the most crucial navigation tools used by explorers were the astrolabe and the compass.
The astrolabe was an ancient astronomical instrument that played a vital role in navigation. It allowed explorers to measure the angle between a celestial body, such as the sun or stars, and the horizon. By knowing the angle, explorers could calculate their latitude, which is the distance north or south of the equator. This was particularly useful for determining their position at sea, as the latitude could be compared to a known position on land.
The compass, on the other hand, was a magnetic instrument that indicated the cardinal directions—north, south, east, and west. While the compass was not new to exploration, its accuracy and reliability were crucial for explorers to determine their longitude, which is the distance east or west of the Prime Meridian. The ability to accurately measure longitude was a significant breakthrough in navigation, as it allowed explorers to determine their exact location on Earth.
Both the astrolabe and the compass were indispensable tools for explorers, enabling them to venture into uncharted territories and expand the boundaries of human knowledge. Their use paved the way for the Age of Exploration, a period marked by remarkable discoveries and advancements in navigation technology.
