Question
Which process of soil formation is described as the
removal of silica from upper layers, concentrating sesquioxides in the solum, and operates favorably in warm and humid tropical climates?Solution
Laterization concentrates sesquioxides in the solum by removing silica from upper layers, favoring warm and humid tropical climates.
