What is soil formation?

• A. A method used to map soil types.
• B. Process creating soils.
• C. The study of soil textures.
• D. The chemical composition of rocks.

Answer: (B)

Soil formation is the process by which soils are created. It’s the long-term work of turning parent material like rock and accumulated organic matter into a soil that develops layers (horizons) and gains its texture, structure, and fertility. This happens through physical and chemical weathering, the breakdown of minerals, incorporation of organic material from plants and animals, and the influence of climate, living organisms, relief, and time. The idea is that soils come from a process that restructures and primes material over time, not from simply mapping soils, studying their textures, or analyzing rocks’ chemistry.
