Question

Name five technological innovations that helped to increase transoceanic exploration.

Answer 1

Technological innovations such as the lateen sail, sternpost rudder, astrolabe, magnetic compass, and improved navigational techniques helped increase transoceanic exploration in the fifteenth and sixteenth centuries.

Step-by-step explanation:

In the fifteenth and sixteenth centuries, European exploration of the Atlantic Ocean was made possible by several technological innovations:

1. Lateen sail: This triangular sail, developed by Arab sailors in the Middle East, allowed ships to travel against the wind, increasing their maneuverability.
2. Sternpost rudder: Created in China in the thirteenth century, this rudder allowed ships to steer against the currents.
3. Astrolabe: The ancient Greek astrolabe, refined in the Middle East, enabled mariners to find their north-south position on the earth's surface by using constellations as a guide.
4. Magnetic compass: Originally from China, the magnetic compass was introduced to Europe in the fifteenth century, enabling sailors to navigate beyond sight of land.
5. Improved navigational techniques: Europeans combined these inventions and techniques to confidently venture into the open ocean, expanding transoceanic exploration.
