Which navigational risk decreased significantly, following adoption of Harrison's chronometers?

💡 Explanation

More accurate timekeeping enabled true longitude calculation because the difference between local time (position of sun) and Greenwich time (chronometer) determines east/west position via timekeeping. Therefore, longitude errors decreased, rather than sextant or compass errors, which concern latitude or direction.

• Which error increases substantially when navigating at high latitudes using a sextant during winter solstice?
• Which risk increased for Babylonian bronze-smiths when riverine copper sources were depleted?
• Which outcome occurred when the Viking longship sail's angle relative to the wind shifted adversely during a coastal raid?
• Which outcome results from improperly calibrated artificial horizon mirrors during sextant celestial navigation?
• Which outcome arises when the pressure of pre-Roman Greek fire underwater is increased past designed tolerances?
• Which outcome accelerated soil salinization when Roman farmers employed irrigation?
