Wandi can tell that the trees on the mountain are very far away, because rather than being able to see individual trees and the spaces between them, he just perceives a big green patch. Which depth cue best describes this?

Texture gradient is the depth cue that describes the fact that objects that are farther away appear to have a smoother texture and less detail than objects that are closer. This is because the spaces between the objects get smaller and smaller as they recede into the distance, giving the impression of a uniform, blurry surface. In the case of Wandi's perception of the trees on the mountain, he sees a big green patch rather than individual trees, which suggests that the texture gradient cue is at play.
