← HistoryWhich outcome results when a 1760s marine chronometer experiences thermal drift?
A)Inaccurate longitude because time degraded✓
B)Latitude errors due to sextant issues
C)Scurvy outbreak since rations off
D)Rudder failure impairs course keeping
💡 Explanation
Longitude determination required precise timekeeping, so thermal drift induced errors via rate integration. Therefore, longitude accuracy suffered because accumulated errors increase over the voyage, rather than affecting latitude or ship functions.
