Which mechanism dictates soil-horizon development during glacial retreat?

💡 Explanation

Successive colonization drives horizon formation during retreat because chronosequence describes temporal stages of pedogenesis; therefore, a gradient along deglaciated terrain reflects soil age, rather than cryoturbation induced mixing, kettle wetland ponding, or esker stream formation.
