Answer:
External and Internal forces.
Explanation:
The earth's relief forms such as Mountains, Rivers, Plateaus etc, are changed because of the action of internal and external forces for example; wind, water or human activities.
Layers of the soil are called horizons. Here are the horizons:
- Humus
- Topsoil
- Subsoil
- Fragmented rock
- Bedrock
Once a soil has developed, it forms layers called horizons. Beneath a surface layer of a plant remains, the topsoil is rich in decomposed plants and animal matter. The subsoil is mainly mineral particles, with much less organic material. The fragmented rock/bedrock is primarily small stones, and beneath it lies all bedrock.
