How did the astrolabe and compass help make sea travel easier?
By measuring the distance of the sun and stars above the horizon, the astrolabe helped determine latitude, an important tool in navigation. Another tool, the magnetic compass, which had been invented in the twelfth century, was improved upon during the Renaissance.
How did the astrolabe most affected European voyages?
What was the effect of the astrolabe on exploration? Sailors could find their latitude with it, and could accurately use their maps. … Sailors could use their maps more accurately.
How did astrolabe influence exploration?
The astrolabe was the most important invention of the Age of Exploration, as seen through the facts that it could determine local time and latitude, measure the angles of stars, and locate the positions of the Sun, Moon, planets, and more components of astronomy.
How did sailors use the astrolabe?
How was a mariner’s astrolabe used? The instrument was used to help determine the ship’s latitude from the height of the Pole Star or of the sun. At night, the Pole Star was sighted directly through small pinholes in the two vanes mounted on the pivoting alidade or rule.
What was the impact of the astrolabe?
The astrolabe was very valuable in the Islamic religion. It helped determine the astronomically defined prayer times, and was an aid in finding the direction to Mecca – Islam’s holiest city. The astrolabe was introduced to Europe from Islamic Spain (al-Andalus) in the early 12th century.
What was the most important historical effect of the astrolabe quizlet?

What role did the desire for wealth play in the voyages of exploration?
Many nations were looking for goods such as silver and gold, but one of the biggest reasons for exploration was the desire to find a new route for the spice and silk trades. … In addition, it also blocked access to North Africa and the Red Sea, two very important trade routes to the Far East.
The magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star. It uses a magnetic needle that can turn freely so that it always points to the north pole of the Earth’s magnetic field.
How did caravels compare to earlier ships that explorers relied upon?
The caravel was an improvement on older ships because it could sail very fast and also sail well into the wind (windward). … Caravels were broad-beamed ships that had 2 or 3 masts with square sails and a triangular sail (called a lanteen). They were up to about 65 feet long and could carry roughly 130 tons of cargo.
How did the astrolabe help trade?
Astrolabes could be used on both land and sea to determine latitude using the height of the pole star and the sun, thereby helping to situate traders within their environment.
How did the Cross staff help explorers?
The cross-staff was a navigational tool used to measure the angle between the horizon and a celestial body such as the sun or stars. By knowing this angle, a navigator could then determine his latitude and direction.
The earliest navigation methods involved observing landmarks or watching the direction of the sun and stars. Few ancient sailors ventured out into the open sea. … Compasses were being used for navigation by the 1100s, and are still the most familiar navigational tools in the world.
What tools might sailors use to find their position at sea today?
Maps, compasses, astrolabes, and calipers are among the early tools used by ocean navigators. In the modern era, these tools have been largely replaced by electronic and technological equivalents.
