✅Explanation:
Slickensides are shiny, polished surfaces found in some soils. They are caused by the shrinking and swelling of clay minerals.
-High Clay Content: Vertisols are clay-rich soils. These clays expand when wet and contract when dry.
-Movement and Shear: This constant movement creates shear forces within the soil, leading to the formation of slickensides.
-Distinctive Morphology: Slickensides are a key characteristic used to identify Vertisols in the field. They often appear as grooved or striated surfaces.
-Agricultural Challenges: Slickensides can make tillage difficult and may affect root growth.
-Global Distribution: Vertisols are found in regions with distinct wet and dry seasons, including parts of India, Australia, and Africa.

📌 Other Options Explanations:
-Inceptisol: Young soils with weak horizon development.
-Gelisol: Soils with permafrost (permanently frozen ground).
-Spodosol: Acidic soils found in coniferous forests.
