Quizplus · Accepted Answer

Vertisols are characterized by their high content of expandable clays, which can cause the soil to swell and shrink dramatically with changes in moisture content. They are commonly found in regions with highly variable moisture levels, such as areas with alternating wet and dry seasons. Oxisols are typically found in tropical regions with high rainfall, while Mollisols are found in grasslands with moderate to high rainfall. Aridisols are found in dry, desert-like regions, and Spodosols are found in cool, humid regions with acidic parent materials.
