← HistoryWhich outcome results when an astrolabe, crafted with brass and used outdoors, measures angular height over time?
A)Corrosion alters sighting accuracy✓
B)Accuracy increases due to stability
C)Components realign with magnetic north
D)Readings are unaffected since compensated
💡 Explanation
Corrosion alters sighting accuracy because the galvanic corrosion mechanism pits and weakens the metal over time due to exposure to moisture and salts. Therefore, astrolabe accuracy diminishes rather than increases, because of wear, rather than remaining unaffected or self-correcting.
