← HistoryWhich problem was amplified aboard 18th-century ships reliant on chronometers for longitude calculation during prolonged voyages?
A)Increased rate errors due to temperature fluctuations✓
B)Decomposition of lubricating whale oil
C)Fogging issues with the heavy glass crystal
D)Saltwater corrosion of exposed balance springs
💡 Explanation
When ship's chronometers were exposed to prolonged variation temperature over long voyages, thermal expansion differences in balance springs caused rate errors because temperature compensation mechanisms of early chronometers had limitations. Therefore increased rate errors occurred. Decomposition, fogging, or corrosion were concerns, therefore are alternative consequences with other likely sources, that would have had different impact on navigation.
