← HistoryWhich limitation increased for mariners using astrolabes on long sea voyages?
A)Cumulative error in celestial angle✓
B)Calibration drift from temperature change
C)Erosion reduces markings readability
D)Parallax shift in displayed constellations
💡 Explanation
Repeated angle measurements introduced cumulative error because small inaccuracies compounded over time using angular measurement. Therefore, positional accuracy suffered on long voyages, rather than mere temperature drift or physical erosion.
