Which mechanism explains why prolonged heat exposure degrades the accuracy of astrolabes used in medieval Islamic observatories?

💡 Explanation

Prolonged heat causes thermal expansion in the astrolabe's brass or bronze components, affecting alignment and accuracy. Because differential expansion distorts the precisely etched angles, navigation errors increase; therefore A, rather than B/C/D, reflects inherent material behaviors.
