Which cue indicates depth by showing objects farther away as closer to the horizon?

The cue that indicates depth by showing objects farther away as closer to the horizon is height in the visual field. This depth perception cue relies on the position of objects in relation to the horizon line. As objects are farther from the viewer, they appear higher in the visual field, and therefore, when observing a scenic vista or landscape, items that we understand to be distant are typically positioned higher up. This effect is often observed in landscapes where mountains or trees appear smaller and closer to the horizon compared to nearer objects like buildings or people, which tend to be lower in the visual field.

Linear perspective, on the other hand, involves the convergence of parallel lines as they recede into the distance, creating a sense of depth. Convergence refers to the way our eyes turn inward to focus on closer objects, which helps us judge distance but does not involve horizon placement directly. Figure-ground organization pertains to how we distinguish an object from its background, which does not primarily convey depth relative to horizon lines. Height in the visual field specifically emphasizes the positioning of objects in relation to the horizon itself, making it the correct answer.
