Soil Profile Diagram - Understanding Earth’s Layered Structure #3646297 (License: Personal Use)

This illustration depicts a simplified soil profile with three main horizons: the dark, organic-rich A-horizon (topsoil), the lighter B-horizon (subsoil) with accumulated minerals, and the C-horizon (parent material) beneath. Circular voids represent pore spaces and organic inclusions, highlighting soil porosity and structure critical for root growth and water infiltration. The wavy boundaries suggest natural layering influenced by erosion, deposition, and biological activity.
