What of these inventions greatly contributed to the expansion of sea exploration in the 1400s?
The astrolabe and the compass.
Why is an astrolabe important to exploration?
An astrolabe is a historical astronomical instrument used by astronomers, navigators, and astrologers. Its many uses include locating and predicting the positions of the Sun, Moon, planets, and stars, determining local time given local latitude and vice-versa. There is often confusion between the astrolabe and the mariner's astrolabe. While the astrolabe could be useful for determining latitude on land, it was an awkward instrument for use on the heaving deck of a ship or in wind. The mariner's astrolabe was developed to address these issues. The mariner's astrolabe, also known as a sea astrolabe, was used to determine the latitude of a ship at sea by measuring the sun's noon altitude (declination) or the meridian altitude of a star of a known declination.

How did the astrolabe impact on exploration?
The astrolabe significantly advanced navigation and exploration by allowing sailors to determine their latitude by measuring the altitude of celestial bodies, such as the sun and stars. This precision in navigation enabled explorers to venture farther from shore with greater confidence, leading to the discovery of new lands and sea routes. The astrolabe's influence extended beyond mere navigation; it fostered a deeper understanding of astronomy, which was essential for accurate maritime exploration during the Age of Discovery. Thus, the astrolabe played a crucial role in expanding the horizons of the known world.
What two inventions made long distance sea exploration possible in the 1400s?
The compass and the astrolabe.
How did an astrolabe change exploration?
The astrolabe revolutionized exploration by allowing navigators to determine their latitude by measuring the angle of celestial bodies above the horizon. This advanced tool provided sailors with greater accuracy in navigation, enabling them to travel further from shore with confidence. By facilitating more precise mapping of the stars and oceans, the astrolabe contributed significantly to the Age of Exploration, fostering long-distance sea voyages and the discovery of new lands. Its impact laid the groundwork for modern navigation techniques.
What tools did Cartier use on his exploration?
astrolabe
What are two inventions that aided in early exploration?
Two inventions that aided in early exploration were the compass, which allowed sailors to navigate based on the Earth's magnetic field, and the astrolabe, which helped sailors determine their latitude by measuring the angle of celestial bodies above the horizon.

Is it true that the two navigational instruments that had the greatest impact on exploration were the astrolabe and printing press?
true
What two inventions made long distance sea exploration possible in the 1400s?
The compass and the astrolabe.
What does improved cartography lines of latitude and longitude compass and astrolabe have in common?
They all made exploration easier
Which best explains how astrolabe made voyages of exploration possible?
With it they could figure out direction and plot a course.
Did Europeans use compasses in the age of exploration?
Yes. In fact, the Song Dynasty (which was Chinse) invented the compass and the astrolabe. The age of European exploration was AFTER Chinese dynasties.
