Final answer:
Interposition is a monocular depth cue that helps us perceive depth by the partial overlap of objects.
Step-by-step explanation:
Interposition is a monocular depth cue that helps us perceive depth in a two-dimensional visual field. It occurs when one object partially covers or occludes another object, indicating that the occluded object is farther away. For example, if you see a person standing in front of a tree, you know that the person is closer to you because they are partially blocking your view of the tree.
