During sunset observations using astrolabes, which limit significantly affected accuracy?

💡 Explanation

Atmospheric refraction affected observations because it changes the apparent position of celestial objects due to the varying density of air (Snell's Law); therefore, angular measurements were distorted, rather than parallax (observer position artifacts), fabrication (tolerances too minor), or precession (too slow).

• Which problem arose from the construction of straight Roman roads across terrain with varied soil composition?
• During the Islamic Golden Age, which limitation arose when using astrolabes near the Earth's magnetic poles determined inaccurately?
• Which limitation influenced Ibn al-Haytham’s understanding of light refraction through spherical lenses?
• Which consequence arose when Inca terrace construction failed primarily due to saturated subsoil?
• Which mechanism increased ziggurat structural instability across time?
