← HistoryDuring the Islamic Golden Age, which limitation arose when using astrolabes near the Earth's magnetic poles determined inaccurately?
A)Reduced precision in horizon altitude measurements✓
B)Distortion of solar altitude calculations
C)Increased errors correlating astral position
D)Non-functional latitude indicator mechanics
💡 Explanation
When an astrolabe's alidade is not perfectly level, horizon altitude measurements have considerable error due to the Earth's curvature because they rely on accurate horizon alignment. Therefore, reduced precision in horizon altitude measurments results, rather than other errors, which don't always require an accurate reading.
