Wendell 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?
A) linear perspective
B) visual expansion
C) texture gradient
D) motion parallax

Texture gradient is the depth cue that describes how the texture of surfaces changes as they move farther away. In this scenario, the trees on the mountain form a texture gradient, appearing more tightly packed together and less distinct as they recede into the distance, resulting in the perception of a big green patch. Linear perspective refers to the convergence of parallel lines as they get farther away, visual expansion is the apparent increase in size of an object as it moves closer to the observer, and motion parallax is the shift in the relative position of objects as the observer moves.
