← HistoryWhich accuracy risk increased as astrolabes mechanically decreased in size?
A)Inaccurate star altitude alignment✓
B)Thermally-induced material expansion
C)Gravitational lens distortion effects
D)Celestial sphere coordinate drift
💡 Explanation
Smaller astrolabes suffered from decreased scale precision because the resolution of graduated markings diminished relative to the tool's physical size, leading to errors in the vernier scale. This occurred on the alidade when aligning stars, therefore, altitude alignment was affected, rather than thermal expansion being a medieval constraint.
