Final answer:
An object's elevation in our visual field is a monocular cue to depth perception.
Step-by-step explanation:
One of the monocular cues to depth perception is an object's elevation in our visual field. Elevation refers to the height or position of an object in relation to the horizon. When an object appears higher in our visual field, it gives the impression that it is closer to us, while objects that appear lower in our visual field seem farther away. This cue helps us perceive depth in a two-dimensional visual scene.
