Which navigation risk increased beyond coastal waters because loss of celestial visibility via cloud cover affected celestial?

💡 Explanation

Uncertain celestial fix on Viking voyages caused increased longitudinal drift, since the mechanism for course correction depended on repeated astronomical observations; therefore imprecise positioning occurred rather than ballast issues.

• During celestial navigation, which outcome affects the accuracy of positional fixes due to slow clock mechanisms?
• Which mechanism causes the iterative solutions in Al-Khwarizmi's algebra to converge to numerical approximations?
• During naval sieges, which outcome occurs when Greek fire's volatile components degrade unevenly?
• Which consequence occurs when Bronze Age smiths repeatedly re-melt bronze?
• Which structural weakness increased the risk of collapse of a Roman castrum wall segment during prolonged siege?
