A monocular cue is a part of depth of perception which allows us to perceive the distance of an object. There are different varieties of monocular cues, one monocular cue is called relative size. If two objects are known to be the same size but their absolute size is unknown, relative size cues can provide information about the relative depth of the two objects. So in this picture and in real life when the moon is closer to the horizon people believe that it is larger due to their relative size, but when the moon is in the sky there is nothing to compare it to so it seems to be smaller. This type of relative size illusion is called a lunar illusion.
