2. Soil Types

Soils can be broadly classified into residual and transported types, each distinguished by their formation processes. Residual soils form at their original location due to chemical weathering, while transported soils are moved and deposited by various agents such as rivers, wind, and glaciers. The examination of soil phases reveals a diverse composition of solids, water, and air, essential for understanding soil behavior in different conditions.
