What happens because of augmentation?

A The horizon appears elevated when observing a bright Sun or Moon at low altitudes.
B The Moon appears larger as the elevation increases.
C The Sun appears larger when viewed against the darker background of the horizon.
D The Moon appears larger at the full Moon.
AI Explanation

The correct answer is B) The Moon appears larger as the elevation increases. This is because of a phenomenon called atmospheric refraction, or augmentation. As the Moon rises higher in the sky, its light passes through less of the Earth's atmosphere, resulting in less bending (refraction) of the light. This causes the Moon to appear slightly larger in size as its elevation increases. The other answer choices are incorrect because: A) is related to the Sun, not the Moon; C) describes the Sun appearing larger, not the Moon; and D) is incorrect, as the Moon appears larger at higher elevations, not specifically at full Moon.
