Quizplus · Accepted Answer

Vertisols are known for their high clay content and property of showing significant expansion and contraction due to wetting and drying. This characteristic results in the development of deep cracks in the soil surface during dry periods, which can cause problems for agriculture and engineering projects. Mollisols are known for their high fertility and dark color, spodosols are characterized by their sandy texture and acidic nature, and andisols contain volcanic ash and are found in areas with recent volcanic activity.
