The complete sequence of soil horizons from the surface downward is called the?

• A. Soil Profile
• B. Soil
• C. Carbon Cycle
• D. Desert Pavement

Answer: (A)

In soil science, the vertical view of all the distinct layers from the surface down to the deeper material is called a soil profile. This profile lays out the horizons you’d encounter, such as the organic-rich surface layer, topsoil, any eluviated layer, subsoil, and the underlying parent material, sometimes extending down to bedrock. Studying a soil profile helps explain how soils form and vary with climate, vegetation, and time. The term soil itself refers to the material as a whole, not the full vertical sequence. The carbon cycle describes the movement of carbon through ecosystems, air, and rocks, not a soil layer arrangement. Desert pavement is a surface feature formed by wind- and weathering-driven processes in deserts, unrelated to the soil horizon sequence.
