All the above.<\/p>\n<p>Refraction is the bending of light as it passes from one medium to another. When light travels from the Earth&#8217;s atmosphere to space, it is refracted by the atmosphere. This refraction causes celestial bodies to appear higher in the sky than they actually are. The amount of refraction depends on the angle of the celestial body above the horizon.
