  • Residual soil: It is soil, which is transformed from rock and resides where it was. An important characteristic of residual soil is that its size of grains of soil is indefinite.
  • Alluvial soil: It is soil which is transported by water, say river or stream.
  • Colluvial soi: It is soil transported by gravitational force. Soil, slide from a mountain falls under this category.
  • Lacustrine soil: It is a type of soil which is found at the bed of a lake. This type of soil is transported by water and reached the lake’s bed. Lacustrine clay and lacustrine silt are examples.
