Question

2 multiple choice 1 point which tool allowed explorers to determine the altitude of the sun while protecting their eyesight? caravel backstaff traverse board mariners astrolabe

Explanation:

• A caravel is a sailing ship, not a navigational tool for sun altitude.
• A backstaff was designed to measure the sun's altitude by having the explorer face away from the sun, protecting their eyesight.
• A traverse board was used to record a ship's speed and direction over time, not sun altitude.
• A mariner's astrolabe required looking directly at the sun, which did not protect eyesight.

Answer:

B. Backstaff
