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.

What we have learnt
- Soils are classified as residual or transported based on their formation and location.
- Residual soils are formed from in-situ weathered rock, whereas transported soils are relocated by environmental agents.
- Soils consist of solid particles, water, and air, and their behavior changes with varying conditions in these phases.
Key Concepts
- -- Residual Soils
- Soils that are formed and remain at the same location as their parent rock.
- -- Transported Soils
- Soils that have been moved from their original location by various natural forces.
- -- ThreePhase System
- A model describing soils as comprised of solid particles, water, and air, where the amount of each can vary under different conditions.
