All the vertical layers or horizons that make up a soil in a particular place are known as the what?

• A. Soil Profile
• B. Soil
• C. Carbon Cycle
• D. Nitrogen Cycle

Answer: (A)

Think of the soil as a vertical sandwich of layers, each with its own properties. The collection of all those layers from the surface down to the deeper material forms a soil profile. It shows the sequence and characteristics of horizons like O, A, E, B, and C, giving a snapshot of how the soil developed in that place. The other terms describe processes or the material itself rather than the whole stacked sequence of layers. The carbon cycle and nitrogen cycle explain how carbon or nitrogen move through ecosystems, not how the soil is layered. So the term that names the complete vertical arrangement of soil in a location is the soil profile.
