Bedrocks, topsoil, and desertification
- Bedrocks are underlining rocks below soils. They are useful in construction works such as buildings, bridges, etc.
- Topsoils are the topmost portions of soils. They are usually rich in humus and organic matter and are therefore very good for agricultural crop production.
- Desertification is simply the loss of fertile soils and their transformation to barren, unproductive lands. Topsoils are lost and soils are rendered unsuitable for agriculture.
