Which consequence results when temperature changes affect a sextant?

💡 Explanation

Indexing error worsens when thermal expansion occurs within a sextant frame, causing misaligned mirrors; thus, angular measurements become corrupted, because the mechanism of thermal expansion alters the geometry, therefore leading to false readings, rather than simple bearing issues.
